I asked how they defined tankie
It's always just a vague "those authoritarian regime supporters" which is a definition that literally all major communist groups will fit into if you're talking about either the USSR or China or any AES. They'll always present it in the vaguest way possible so that to the uninitiated it sounds like there are some communists who don't fit into it when in reality that's not the case at all, the people who don't realise that are the target of an attempt to try and prevent them from moving further leftwards.
Trots support the USSR post-Stalin and even trotsky says he'd have done everything stalin did. MLs obviously support both China and USSR and AES, maoists support USSR and pre-Deng China. This is 99% of communists fitting the definition.
seriously?
