All of your fears of tankies throwing you in the gulag are predicated on some sort of revolution happening. Do you really think that’s imminent?

Irrelevant. Utterly irrelevant. The proper revolution requires there to be no people who would put people in gulags, or people who would need to be put into gulags. Advocating for, justifying, or excusing gulags in the name of the revolution thus is counterrevolutionary. And yes it's not imminent, it's beyond several horizons. (inb4 you call me gradualist and think that's an insult).

There’s no class consciousness in the US, there isn’t likely to be any anytime soon

Largely because McCarthyism, the perpetuation of which tankies play right into with their Soviet nostalgia and authoritarian state capitalism. If in 50 years files get declassified and it turns out that the US government has been pushing tankie idiology and structures as some kind of COINTELPRO operation to disparage the broader left I wouldn't be surprised. The consequences of you actions, man, have a look at them.
