You're right, and I think I know the guy you are talking about. I interacted with him once to make the point that he should calm down, even when talking to the other side. He told me to get lost (in more colorful language than that), even after I explained I wasn't a Trump supporter.
I made a meme about the experience chastising him for it, lol, and it was one of the most successful in the PoliticsToo stream that month.
