(Just my own two cents: I’ve never so much as posted in GD.)
I think Gaudere and the other moderators have it right (see the moderator post in the GD thread of 10/30 at 04:01). JDT has a right to debate his case in the appropriate forum without getting flamed or dragged into the Pit just because his arguments are particularly inane. Fair’s fair. As Gaudere pointed out, other posters argue equally silly propositions elsewhere on the board without getting dragged into the pit. If JDT can maintain the facade of a scholarly debate, then he’s meeting all the same requirements as other serious posters.
The integrity of the SDMB isn’t violated by ignorant people posting ignorant opinions. After all, the purpose of all this is supposed to be about flushing out and confronting ignorance. However, the integrity of the SDMB is violated if the moderator’s can’t enforce the rules of the forum.
I was on another message board where the rules were uniform across the board: Argue anything you want, but never insult. You couldn’t even use the word “ignorant.” Any post with an insult was simply deleted outright. It made for a weird environment. Any jackass could post any preposterous, distorted, bigoted point of view ad nauseum so long as he didn’t insult, and the posts of his opponents were consistently deleted for inevitable insults and expressions of disgust. Nonetheless, Gaudere has a good point when she[?] says “I generally expect that GDers can thoroughly destroy the arguments of someone who can’t back up their statements without posting personal insults.” That’s how we did it on the other board. Debate the other person head on: Pull out some scientific factoids that refute some of JDT’s “facts,” and repeatedly insist that JDT address them. Or ignore the fellow outright.
I thought of posting to that thread and having some fun. I was going to agree with the fellow. Something to the effect:
“Yes, I too have heard that people with circumcisions have shorter attention spans and poorer memories. And they have higher rates of tuberculosis, piles, and scoliosis.
“In addition, native tribespeople have been known to stretch their foreskin as a survival technique. In the field, certain aboriginal tribes have the ability to pull their foreskins over their entire bodies to camouflage themselves from the enemy. And the great Native American chief Geronimo was said to have parachuted to safety off a cliff on one occasion using his foreskin.”
I don’t know if this kind of silly sarcasm is allowed in GD, but it can be quite effective as a debating tool. Make inane assertions of your own and defend them just as vehemently as JDT defends his.
In other words, lighten up a little bit. The guy’s a crackpot. Have some fun with him. Or ignore him if he troubles you so much.
