I'm not really interested in defining them or getting into that kind of argument here (not being a Communist, I don't want to defend it).
...but I believe Market Socialism is a thing. Capitalism is (in Marxist doctrine) considered a stage of Communism, and that these discussions often overlook Vietnam...
...Vietnam also has a system of Market Socialism, they've just almost resolved homelessness and have no housing crisis because they have a land redistribution system for anyone who wants to go into farming.
... so like, whilst I don't like Tankies AT ALL (they all demand you read a specific 1000 book list before even having a discussion)... I do think anti-communists are also annoying and often under cooked/biased on historical facts.
To use an analogy being anti-tankie often comes across as basically saying we need to reconsider what the alt-right are saying during the Trump era.... And exceedingly often comes down to "a tankie once called me a name I don't like".
In short - in comes across as reactionary (rather than thoughtful/legitmate). I don't like anti-tankies because they're having a reactionary response rather than just going "those guys are dicks, but I understand within a Capitalist society"
Instead anti-tankies go, "those guys are dicks for calling me that of all people, I'm going to form a club to complain about it... Even though billionaire crony Capitalism is really the problem right now".
So yeah, I don't like either of them, but I understand uptight commies better than I do the reaction to them. I can hide and block the commies pretty easily.
