All links in comments are nofollowed.
Nofollowing isn't enough to stop determined SEOs with lots of time on their hands. A nofollow link is still decidedly better than no link at all, because it gets a couple of clicks of traffic and maybe, maybe will be picked up by someone else as a follow link.

Presuming he is smart enough to understand the implications.
>perhaps relegating the race/gender/IQ trifecta to the same status as religion and political discussion, or to accept the likely degradation in discussion.
I'd prefer to accept the degradation. "X racial subgroup is better/worse in some way than y racial subgroup" is one of the unnamed Things You Can't Say and I see no need to censor it here, even if the discussion makes me uncomfortable.
Right, sweeping it under the table is never a good idea, but I don't know what else can be said about it that hasn't been beaten to all hell and back here and everywhere else. It's not like opinions are going to change, and I, for one, get nothing out of it.
It is informative to know how other people think about these things, so you have a point. I do worry, though, about what type of people will be attracted here by this type of meme.
edit: Then the strategy aswanson alleges occam is pursuing is totally misguided. Maybe a little note on the bottom of the comment box that all links are nofollowed would prevent any further such attempts.
