@nihilist, i also dont think antifacist action makes racism less popular. i also dont think that is the point. it seems to me that the important factor isnt how popular x idea is, but how powerfully that idea is imposed on the world, though of course the two are interconnected. indeed racism is a very powerful idea itself, as it brings people together united in a common cause, a common fear, and a common anger. i dont see antifascist action as something that 'changes peoples minds' but as a way that certain people, people who say are antifascist, enact their will on the world. but i dont live anywhere that it is done, and i dont really do anything that could be considered 'antifascist' myself.
to come at it from another angle, i dont really believe that disengaging with society will make society go away, or weaken society in any meaningful way, but that also isnt the point. i dont want to disengage with society as some sort of debate, to prove that i right and that my way is better. the point is to move myself away from society, to create distance and so autonomy and independence. to change *my* world, not *the* world. similarly i could see someone arguing that the point of antifacist action isnt to make racists less racist, but to keep them away, or to maintain a level of power over racism.
also the idea that 'debating' and 'questioning' neo nazis, or indeed anyone, out of there position as a means to tackle a shift in power i think is laughable. to have your ideas questioned you have to allow them to be questioned, you have to allow yourself to be vulnerable to a minor extend, and thats not something most fucking anarchists can do, let alone neo nazis.
