Cussing doesn't show animus to anyone. That's a massive difference. No one has been murdered, lynched, humiliated, raped,had their vote stripped, brutalized, enslaved, gassed, interned, exterminated, falsely executed, fired, denied equality under the law, paid less, ignored, or had their families blown up because of cussing. The fact that you think this is even remotely comparable shows that you're clearly not someone subject to sexism, racism or homophobia. Amazing that anyone would even have to explain this
