Why are you rude?

[The Valkyrie]

I didn't create this thread because someone was rude to me.
I just don't understand why it's considered acceptable here to use vile language even if you strongly disagree with your opponents.

I’m rude to people when they’re being idiots, when they start being insulting or smug, or when they’re generally trolling.

However, I swear a lot because I swear a lot in rl. It’s my personality. And I don’t get to do it often in a professional environment.
