Lawrence Summers, the controversial former president of Harvard University, has been replaced as the planned speaker at a UC Board of Regents dinner next weekHolocaust denial is given academic legitimacy at an Ivy League institution, while asserting national sovereignty and entertaining the idea that the "men are from Mars, women are from Venus" aphorism extends beyond the toilet-seat battle are so hateful that educational omertas must be enforced upon them.
after complaints from faculty members. 
Columbia University said it does not plan to call off a speech by Iran's president despite pressure from critics including the City Council speaker, who said the Ivy League school was providing a forum for "hate-mongering vitriol." 
The Columbia Political Union voted late Monday night to cancel Gilchrist’s [Minutemen Project founder] Oct. 4 appearance, the New York Post reports.
The student group said in a statement that "it has become clear this event cannot take the form we had originally hoped it would and could not effectively accomplish the goals we had hoped it might."
Last year critics questioned Columbia’s commitment to free speech after Gilchrist was physically and verbally attacked by student protesters. 
What else really needs to be said about the state of secondary education (at least on the soft-sciences side) in the US?
That Columbia President Lee Bolinger launched into the Iranian President does not negate the contrast. If Gilchrist or Summers (though since he wouldn't be dealing with the subject relating to his 'hate speech', this does not even apply to the latter) had to absorb the same sort of harsh introduction that Ahmadinejad did as a condition of being allowed to speak, would that opening of debate had made their respective appearances worthwhile in the eyes of the pressure groups (and faculty) that lobbied for their excommunications? To the contrary, such 'inflammatory' rhetoric only made the whole Ahmadinejad ordeal an even more ridiculous dog-and-pony show than it already was.
