I am a big fan of you and Thomas. And I love reading your discussions on a topic and have read most of them. I tend to agree with your arguments more but I must say that Thomas is very respectful while disagreeing and I haven't seen him call you a racist. Feel free to link to his comment where he does and I will stand corrected.

The remainder of the thread had no substantive disagreement, just questioning my motives for discussing a factual claim.
I still don't believe you. You're right: the comment you cited was a moment of incivility (specifically: I was sarcastically dismissing you). I don't believe that you think white supremacists are mostly factually correct. I think you get a rise out of zapping this particular raw nerve, and feel like you're so gifted at rationalizing message board comments that nobody will pin you down on that.
I don't mind the attack, I just wish it were easier to tell when you were interested in intellectual discussion. Intellectual disagreement is fun, but threads like the one I linked to feel like getting rickrolled. Less fun.
