I mean, there's also a reason that Marxism-Leninism and Stalinism was historically referred to as "red fascism": Soviet ultra-nationalism, fetishization of violence, authoritarianism. They were very cosy with the Nazis when it came to carving up Poland between them.

Yeah they're internet trolls that picked up the mantle, it's not like they've done the work do deal with their internal issues.

While not everyone agrees, it’s not as if the description of Russia as a fascist state is completely pejorative, see https://en.wikipedia.org/wiki/Fascism#Post-Soviet_Russia and the linked Ruscism article.
