I'm thinking more of the hideously deformed Anarchist Workers Group.
The AWG wound up in 1992, an 18 year old entering the movement today would have been 3 when the last published anything. They had a maximum of 30 members and existed for les than four years. I don't understand why they still haunt the imaginations of anarchists in Britian in the manner they seem to above. Learn what is to be learned and move on.
(For the 18 and older year olds see http://www.struggle.ws/awg.html for a partial archive of AWG material and analysis of their collapse).
it also has to be understood that a large number of the AWG's members were coming from an SWP background, that must have had a relationship with their politics.
