I'm utterly convinced fascism as a term is only employed by western supremacists at this point.
Euros invade the global south: YAY
Germany invades western europe: BOO
I think about that a lot. Both the redefinition of fascism to mean the specific policies and behaviours of the Nazi party, and the fact that the EU successfully achieved quietly and without much resistance what the Nazis attempted loudly and brashly.
The term red fash specifically has absolutely no meaning beyond telling us that the speaker has no interest in understanding political ideology. It's kind of like tankie but more dumb.
