J. Edgar Hoover's pronunciation of communism.
"Senator, I think that commonism is as serious a menace to the United States as it ever was if not more so."

The naive belief that everyone should be "normal" and the same and that if anyone tries to be an individual and stand out they're stupid or weird.
Guy1: Why do you wear your clothes that way? It's so stupid and weird.

Victim: Yeh? Well I try to be an individual and stand out. I'm also a real ass hole to people I don't like so you better watch your back, you fucking commonist! Commonism, psh. Bitch nigga!
