Harvard blocked a Reagan visit.
I don't remember that, but I now they're blocked several visits of conservatives.
The incredible hypocrisy, is Harvard's attitude about their former President's remarks about women, which eventually led to his resignation, and the fact that they're opening their arms to Khatami, who was president while women were stoned, hung and tortured in prison; a country where women are told what they can wear, how to act, and have to ask permission from their husbands to travel alone.
Apparently, that's all fine, just don't say anything about the differences between men and women in math and science.
