I suppose it is time again to remind folks about my comment moderation policy, which is: I don't moderate. I certainly strongly request that commenters remain civil, reasonable, and respectful. But, the combination of being lazy and not easily offended cause me to almost never moderate on content, except to eliminate obvious spam.
Readers should remember that the existence of comments from morons does not mean that I in any way endorse them - I simply have no desire, paraphrasing Napoleon, to interrupt a moron when he is proving himself to be such. I have never fully understood folks deleting comments of foul-mouthed idiots who disagree with them in spectacularly stupid ways -- aren't you just helping your opposition? The only folks I am ever tempted to moderate are those who agree with me, and do it poorly. Back in college, I used to much prefer a group argument when I was the only person on my side, as I always found that people who leaped to my defense did more rhetorical harm than good.
