I think people very generally miss the very important subtlety that words never hurt people. It's the intention behind the words that hurt and you don't need words to communicate intent. So banning/censoring words really doesn't do much other than placate the people who just wanted to feel involved in changing the status quo.

Compare that to a punch to the face. It really doesn't matter if someone was just joking or angry with you, 150 psi to your jaw is going to do damage.
