Words aren't violence. and naughty-racial words, are words.
I actually want people to be allowed to say those things, why? Because if someone says it out loud, unapologetically when they say they hate those n-words in their schools. Well now I know who to stay away from.
So if I tell your friends, school and employer that you are a murderer, a pedophile or about your dirty hobbies, that is perfectly fine with you? You do recognize those things are punishable by law?
