I know someone like that. He's an outspoken communist and sees anything anti west as inherently good. It's a very black and white world view.

He also thinks winning an argument just means outlasting the other person and shouting. I once observed him argue tabletop game mechanics or a half an hour before we realized he doesn't think removing cards from a deck changes the probability of getting one of the remaining cards. He can't hold down a job and ironically, he's in digital marketing.
