This kind of approach just betrays a lack of historical understanding. In the past 100 years it's mostly been anarchists getting massacred by state socialists. Is it odd thatr some anarchists should get fed up at this, and try to stop this happening?
Absolutely, however I'm having a hard time recalling the last time I saw any trots advocating murdering anarchists on my local stall in town. I must've missed that meeting.
Y'see if I thought that fighting anarchists was the first task in fighting fascism i'd be out day and night scalping 'em, how come you're not advocating militant anti-fascist tactics against the trots if you're so certain in your beliefs?
