That being said - Isn't it interesting that the people he ignores for being bad people, are actually much more respectful of others than he is? I mean the rest of us are actually having a conversation and trying to learn something here... and he's just being insulting and advocating writing off anyone who doesn't agree with him.
In my opinion he is not wrong, but he is not being productive either. I will also strongly condemn anyone who uses the initiation of violence against other people in order to get them to obey their arbitrary rules but I might try and persuade them with an argument first. Perhaps he feels he exhausted that option..
