I thought Texrat handled it very well. Profesionally, actually. I stayed up till 5 am, and I just got online again right now (so what happened after is still sketchy to me). Bummer was taking abuse, sure, but it was pretty much deserved (at least until 5 am, I don't know what hapenned after). He was repeating his arguements even after he was told that they weren't relevant. And he was dishing out his own eloquent abuse, at that.
Texrat did what was right. Based on previous experience, he allowed the debate to go on, jumping in frequently to remind everyone what was going on, and to cool the debate when it got heated. Bummer can claim victory all he wants, but when the thread was developing Texrat took the appropriate and correct decisions.
Hats off to you, Texrat.
