Can you explain a little more

Can you explain a little more why you think that it is impossible to shift a movement further to the radical end of the spectrum without authoritarianism? Is this not, for instance, what the black bloc strategy was invented to do? I mean, isn't this what anarchists attempt to do in general?

I'm pretty interested in what you have to say, so feel free to email me if you don't like @news comments. My email is in the first article of the first issue of HG at www.wildism.org/hg/1/1/
