Yeah, that’s fair. I was guessing that that chump thought that “red fascism” was a thing, and if somebody is going to use that phrase unjokingly then I’d expect them to recognize actual fascist symbols.

If somebody like you asked respectfully what the symbol was then I would have responded in kind.

But you didn't have a hostile attitude about it. And he used the word tankie as an insult right off the bat, so you can guess his politics.
