I went to a Marxist reading group one time when I was in college. The guy who ran it was a huge tankie. Stopped going after the second meeting because everytime someone brought up a point he would preface it by saying "well, the Socialist Appeal says…" He was basically just using the reading group as a recruiting outlet.
One time I was on yikyak and someone posted a hookup message, basically 'discreet gay sex.' The email was comrademarx7 or something so I'm almost certain it was him.
