The following was inspired by a recent interview with Noam Chomsky  which was coordinated by people working through the anarchist subreddit  at Reddit dot com.  
As a chronicler of modern history, Noam Chomsky is something of an  icon.  The number of people he has influenced with his writing in favor of general social justice is probably beyond  measure.  He has highlighted things with his political writings  that may otherwise not have received the attention they deserve, and I'm  sure he'll be the first to admit that they still do not get all the  attention they deserve.  He's talking about very serious things in terms  of apartheid, genocide, and war.
Unfortunately, with his latest interview, he has proven that simply  being aware of many serious problems does not necessarily give you any  real insight on how to effectively deal with them.  And I might point  out... some of the issues he brings up in passing, like environmental  degradation, seem to be thrown in as a token for the effect of appearing  comprehensive.  On the particular subject of environmentalism, for instance, he offers  nothing substantive with his suggestion that anarchists should be  concerned with such issues.  Unsupported by what human beings have already done, he suggests that humanity will be  able to technologically engineer it's way into a more peaceful, less polluted, less devastated  world.   Perhaps so, but that's pretty vague, at best.
What really stuck in my craw was a couple of points in particular.  The  first was his explicitly stated support for "mild reformist  tactics."  In a more ideal world, under more ideal conditions, this  might be as reasonable and cool-headed as he intends it to be.   Unfortunately, this is a far from an ideal world and he should know that  beyond a doubt.  If I may be so bold, as  someone who tries to highlight these issues on a regular basis,  please allow me to try and summarize some of the pressing issues facing  humanity today.
A)  More people are starving today than at any other point in history OR  pre-history (both in total numbers and per-capita).  It is estimated  that 1 billion people live with issues of chronic hunger.  That's more than 1 out of every 7 people, alive today, who are aren't getting a basic human requirement for life.
B)  The environment is being ravaged in no uncertain terms.  The myriad  of issues are almost too great to even begin listing... climate change,  ozone depletion, ocean acidification, deforestation, desertification,  and the Pacific trash vortex are just the starters of what's seriously  jeopardizing the ability to sustain life on this planet.  Indeed, we are  currently experiencing the most devastating period of mass extinction  since the dinosaurs died out.
C)  War.  Although sometimes related to the two preceding items, war by  itself is an occurrence which effects the lives of hundreds of millions  of people.  Around the world, in forms old and new, wars rage.  And the  weapons which could destroy every person on this planet are being  improved upon and spread to evermore groups.  One could debate the  effects of global thermonuclear war or a limited strike, but it would be  a fools errand.  The potential for global devastation must be defused  -- but proliferation continues.
D)  The general conditions of life for billions of people (even if they  are not immediately and directly effected by hunger, war, or a polluted  water table) is such that many are still veritable, if not actual,  slaves.  Never mind the millions who get cycled through the  prison-industrial complex each year (or the constant police presence in every American city), many people have few alternatives beyond working on  the assembly line for all their waking days.  And that's even before  considering the most atrocious sweatshops or mines or fields that many  people are forced to work in.
In the light and shadows of this reality, Chomsky calls for mild  reformist tactics.  He even digresses into talk about healthcare  reform!
This is the icon of the left (who even has the ear of would-be radicals)  that is propped up as the preeminent intellectual of our era.  This is,  from what I understand, the most quoted person alive.  But what is he  really saying that will actually inspire a much needed difference?  And why  on Earth would anarchists, of all groupings, try to claim him as one of  their own?!  In this recent interview he even reaffirms his support for  strengthening the state!  The situation is beyond ridiculous and even  has Orwellian undertones.
He actually goes out of his way to insult the modern anarchist movement  as it exists within the confines of the United States.  He suggests we  haven't got our act together because we haven't been able to muster the  same large protests as some European anarchists -- but he fails to  point out that we face a far more militarized and draconian police force  in this nation.  We suffer high levels of infiltration in our daily  lives and then suffer state violence at protests merely for showing up.   And he certainly isn't giving any support for the thousands who do  actually show up and protest things like the RNC, DNC, G20, et cetera.   If he's going to criticize us for a lack of it, then maybe he should  give us some support in these regards and not dismiss us like the  mainstream media.  But he is not at all talking about protest (which has  historically brought about great change), he's talking about "mild  reformist tactics" and "small steps."  He wants us to be reasonable, and  practical, and work on things like healthcare reform or worker control of  the factories with the support of the state.
In my attempt to be thorough allow me to digress... I won't even comment  on the likelihood or the potential harm that could be caused if  industrial consumerism was perpetuated by worker control of factories  with the support of the state.  But the focus on healthcare reform as a  worthwhile effort (and it would certainly be hard to achieve and  maintain) needs to be commented upon...
It is true that "The radically inefficient, privatized, unregulated  healthcare system is extremely harmful to the people, except the  wealthy."  But why in the world would we trust the U.S. government "to  develop a sensible national healthcare system?"  Even if it does somehow  get implemented, for all our reformist efforts, are we supposed to  discount the rising probability of the economy in the United States  crashing in a way that the Soviet Union never did?  I'm reminded of all  the people who established pensions through their unions only to find  out one day that all the funds have been magically deleted by the stroke  of a bankers pen.  So how much effort should we put into establishing such  things?  Even if fully successful, what will the long term effects of such placating policies  have on the general public?  Don't get me wrong, I think people should  have health care -- but we will need far more fundamental change overall  before we actually get it.  And healthcare won't mean much if any of  the larger problems we face come to their logical outcomes.
In all honesty, even I have suggested ways that reformism could have a place in creating long-term social change for the general benefit of  humanity.  But it's not an either/or situation, and that's how Chomsky  frames it by discounting and failing to promote regular demonstrations of people in the  streets.  He does not speak to the practicality of such mass movements  and the manner in which they can inspire reform like no other action.
The problem with reformism isn't really that we want too much in terms  of issues being resolved, the problem is that we NEED these issues  resolved, in short order, for our long term survival as a species.  We  need a general movement of people in the streets making it clear that we  see through the fascistic oligarchy that is wreaking havoc around the  world.  Simply put, we need the masses in the streets making it clear  that we won't take any more of the rampant general corruption and  villainy which presides over our daily lives.  And we need to get into the  streets sooner rather than later.
Piecemeal reformism without mass  protests won't do anything because we all know, everybody knows, the  government can simultaneously undo progressive reform while it concedes a  hard won reform somewhere else.  The question isn't whether or not we  should be in the streets, the question is how long we should be there  and how much change is needed before mild reformist tactics make sense.   My guess is that we'll need to be there a long time, under hard  conditions, and we'll need to go back often.  The slogan of  the anarchists used to be "perpetual revolution!"
Mass demonstration protests, i.e. general strikes, are not easy  undertakings.  But their great potential makes them more practical in  terms of a risk/reward analysis.  It may seem somewhat counterintuitive,  but it's easier to protest in mass with solidarity than it is to  spend every free hour writing to (or campaigning for) your particular  politician.  And mass protests show real sacrifice and commitment.   Without showing that commitment, without people taking risks and making  sacrifices, the politicians can ignore and manipulate at their  discretion because there is no consequence or embarrassment for them.
And we must demand a total revolutionary change in the social structure  because those in power may try to only meet us half way -- and that's a  start, a reformist start.  Fortunately, there are many relatively depoliticized  groups of people who will be willing to start undertaking these mass  demonstration projects with us -- the unemployed, the evicted, the  victims of the police state, the unions, the people who lost their  pensions, the anti-war activists, the health care reformists, students,  environmentalists, and on and on and on.  We do need to organize with  these people and we need to make it clear that we are working for a  thoroughly comprehensive change of a thoroughly corrupt system.  Yes  there will be resistance.  Yes it will be difficult.  But the longer we  wait to take to the streets the worse the aforementioned problems will  get and the harder they will be to remedy.
I see no point in further discussing Chomsky or paying any attention to his pacifying drone.  His proposed solutions and methods of acting are hollow.  He sounds calm and reasonable but he's an empty academic suit and the epitome of an ivory tower intellectual with no practical advice for effectively bringing about real change.
In regard to how we long should stay in the streets, I will close with a  rallying cry from the Paris insurrection of 1968... "Underneath the  paving stones, the beach!"
