But seriously. It's just about civility. You have to keep a respectful tone when you disagree. People think that as long as you're not using cuss words and directly calling someone an idiot, you're good to go. But it doesn't work that way. There's lots of ways to be disrespectful without swearing at someone.
Chris found out he can't be dismissive of other people's opinions and needle them, despite the exagerrated "who me? I'm not doing anything wrong" routine.
