Because the bots/trolls/feds have shifted over to driving a wedge between leftists to keep solidarity from occurring. Thus "tankie" is being thrown around heavily, people constantly bring up early Soviet support of the nazis as a reason to say "tankie=nazi" while ignoring that tankies (sue me, it's a real term that has uses) is a broad term for all "authoritarian fascists," many of whom came after the nazis, were very anti-nazi, and like all historical figures often had a mix of good and bad qualities.

Certainly its funny to harp on tankies while America falls to literal fascism. Who ever could benefit from scape goating and demonizing communists? Who historically, poetically even, is the famous first victim of fascism due to the strong threat they represent?
