Borat - Sacha Baron Cohen's character - is a troll and creates comedy by highjinks and miscommunication. It's done from a place of love & truth.
Trump supporters - aka nazis - flying a nazi flag but claiming it's trolling or to annoy the libs - that's not trolling. That's not comedy. That's terrorism being disguised by their claims of comedy. That's intimidation, and exuberant threats of violence and more,.
It's made "ok" only if you prefer civility over punching a motherfucking nazi.
