The Academic Left continues to pound Harvard President Lawrence Summers for suggesting that perhaps innate biological differences are the cause of fewer women in the sciences. You can find a good deal of background material here; here is an article discussing the free speech implications.
This is the exact opposite of the Ward Churchill snafu; Summers was engaging in a lively academic discussion, and highlighting a theory that could proven or disproven by experimentation. There was no hint of the polemical in Summers' remarks; he was not suggesting that women weren't smart, just that they disproportionately choose other areas of study, and perhaps we should find out why.
Summers has caved and apologized multiple times, but clearly some radicals on the Harvard faculty want his head. Bloggers vs. Eason Jordan was called a witchhunt by many, but was not - this, however, is quite another matter. I'm sure we haven't heard the last of this.
