tankie:

(politics, slang, derogatory, by extension) A supporter of authoritarian policies and actions by the Soviet Union, China, or other nominally socialist governments.

fascism:

Any right-wing, authoritarian, nationalist ideology characterized by centralized, totalitarian governance, strong regimentation of the economy and society, and repression of criticism or opposition.

So yeah, Hexbear isn't full of fascists, it's full of tankies, which are just fascists with a socialist coat of paint. The fact that I'm doing this because I was actioned by a moderator acting as a tankie commissar doesn't change the validity of my reasoning as to why being federated to Lemmy.ml is a problem.
