It doesn't, but in this thread's we see a simultaneous claim of "We aren't tankies, of course Stalin and Mao are not good examples of communists" and "Eastern european people were better off under the USSR". Of course, I don't think the same people are making both claims, but just the fact that some people can claim the latter and not get collectively shunned is indicative of a huge problem in leftist spaces, it's disgusting frankly. Tankies are significant force, at least partially representing leftism to everyone else.
