It's like banning shovels because someone can get hit with a shovel. It's not a language problem, and it cannot be solved by chopping the language up on the Procrustean bed. All it's going to do is annoy people and rally them against what used to be perceived as a good cause. And guess what, sometimes one needs to get hurt by being called a fucking idiot especially, if they act like a fucking idiot. Real life is not kindergarten. You have responsibility, not just rights.
