I think you're sensitive because he *is* offensive. And I call bullsh!t on him not realizing it's a problem. He damn well knows when he comes across as an insensitive, rude, know it all but gets off on playing the "What? Me? What did I do/say?" card because it lets him, yet again, point out that you're stupid/clueless/over emotional/etc. or whatever the insult du jour is. Seriously.
