Good point, tankies isn't a very well know term.

Telling new users they shouldn't listen to the FooBars when they say "don't vote for Genocide Joe, I'm your friendly neighborhood communist btw" doesn't directly convey why the FooBars can't be trusted. I think most people on Lemmy agree that communism isn't the enemy.

Maybe instead of tankie, we should use a more known and direct descriptor: don't trust the dictators.
