If a man screams "slaaaaaaaaveeeee" in the forest, and no one is around to hear it, does it still cause offence?

The answer is yes. It does. Because it's not about sparing the feelings of the person who hears it. It's about controlling language to control thought. It's about control.

Think about why people go looking for things to be offended by. If they only wanted to feel welcome would they really go looking?
