Which is on brand for them. The original “tankies” were cheering on the Soviets violently crushing uprisings by other communists for attempting to practice the “wrong kind” of communism, AKA “Anything other than complete submission to Soviet oppression.”

That’s the sole identifying mark of a tankie: a desire to crush dissidence of their peers through violence, particularly if their victims share their professed economic ideology. Tankies aren’t communists: they’re fascists cosplaying as communists.
