As a marxist, I’m myself tired of how tankies deals with criticism. And I don’t even understand how people can stay with “Stalin was not so bad”, knowing that he never planned to apply the last state of the Communist theory, and even if it did, massacre are not acceptable (sounds obvious), same applying with China and their open market.
In my country (France), Stalinism isn’t a thing, all communists are against what happend in USSR, and most are anti-china.
