Them: I am a bastion of good manners and common decency! Tell me one instance where I have been anything but unfailingly polite!
Me: Uh, how about reason 1, reason 2, reason 3?
Them: No, I disagree. I do those things but have no intent to change. People are just mean to me for no reason!
Me: They'd probably respond better if you didn't do 1, 2, or 3. Those things are really bad manners.
Them: I disagree. After all, I am a bastion of good manners and common decency!
Moderator: Except for the fact that you keep doing 1, 2, and 3. You should really shape up.
Them: You cannot point to a single example of me doing anything wrong!
Me: Well, there's always 1, 2, and 3....

Edit: "I disagree."

I'm sure you do, but like the man who insists on his absolute moral right to chew with his mouth open and clip his toenails at the dinner table, it doesn't matter much what you think. He doesn't get invited to very many dinner parties. You get progressively banned from every place you go. The whole world treats you like an asshole, and no matter how much you try to blame the world for this fact, the truth is that you are the cause of this.
