"the massive downvoting of the parent comment is a dishonest enforcement of political correctness."

I don't read Sailer's blog, but from what I understand it's mainly devoted to proving that African-Americans have lower IQs because of inferior genetics. Now you might say, well if this really is true, then wouldn't denying it be intellectually dishonest? Here's the thing though. The black-white IQ gap has been almost entirely explained by controlling for SES and other factors. Anyone who spends all day quibbling over the last two or three points clearly just has an axe to grind for other reasons.
