I see nothing wrong with cursing. Cursing is an expression that give more substance to something you want to say. Some people see it as a general insult. But is kind of dumb to think that words posted online can hurt. We are all digital entities here, so words can't hurt.

Once thing is to tell to my best friend IRL "your mother is a cunt" straight in his face (even knowing his mother well, she even make me best apple pies). That will be a real problem.

And another thing is to say to some nym online that is a cunt.

You can even say "cunt" IRL in a funny way...

I really think that this auto-censoring is coming from other sources that we were trained to behave like that because of X or Y stupid rule.
