Cultured people have no need for such words in public discourse so I'd rather not see either of them or the need. People are judged by the words they use.

Cultured people? I'd certainly argue that words which people feel are "uncultured" strictly DO have a use case.

It's as if you're saying "smart people only color inside the lines." Take a step back.

The usage of those words is to accurately convey the speaker's emotion. If you don't see any use in that then that's your problem.

There are far better words availble than to use those often referred to as "gutter talk".
