go back and read his posts and your replies. somewhere you decided this guy was attacking you and i don't think he ever was. in fact, he seems to be agreeing with you, most of the time. i think you're being (understandably) defensive.
i think he misread or misinterpreted the tone of one of your posts way back in the thread, actually, and has reacted defensively and with a bit of animosity to each of your posts since then. unfortunate bit of a misunderstanding, i think.
