Their positioning, further to the left than subreddits like r/communism, r/socialism, and r/Anarchism
I like how they use informedtankie as their first example of a tankie space, then act like /r/communism and /r/socialism are somehow less so? All three literally share moderators, and have shared many former moderators who are now spread across hundreds of projects on the site.
It's so fucking badly researched. They know literally nothing about socialists or the fact that among marxists there's very little issue with "tankies". There is no separation or division. They seem to think that there is.
They'd have a fit if they realised Corbyn upholds AES, advertises the Black Panthers, or Dianne Abbot defends Mao on national tv, or John Mcdonnel waving around Mao's little red book in parliament. Like wtf do these people not know what marxists are? It's like they have literally never encountered actual socialists before and really only have a particularly vague understanding of any of this shit. I can't think of a single marxist figure in the mainstream (for a marxist) that wouldn't fit their definitions of "tankie" if they ever actually inquired as to what any given marxist believes. The only real difference between any of us is our position on China diverging between ML, Trot and Maoists, which isn't really that divisive at all.
The only group that anyone really has any beef with are the gonzaloites.
