I find it difficult to hold a conversation with someone who disregards everything I say to make me look like I'm wrong using vague points which are irrelevant to the core subject material.

Just go ahead and say I make you uncomfortable because I'm speaking directly to you in this condescending manner. it's not the attitude, but my being right about YOU that bothers you. But don't stoop to petty lows, trying to make me look like the idiot. Anyone here with an IQ over 50 knows it too. So I might not be so liberal about speaking on other's behalf.
