First, there was the controversial idea of hosting Bush's Presidential Library at Southern Methodist University in Dallas. Now, SMU apparently got picked to host an "intelligent design" conference. My favorite quote from the SMU faculty:

Other biologists compared the conference to a presentation by Holocaust deniers. Would the university allow that to happen?

That is an interesting question. It is clear that official government censorship should never be tolerated, but a private university like SMU has the First Ammendment right, as well as a responsibility, to limit the groups with which it associates. Clearly the University would cancel its hosting of the event and return all fees, even at this stage, if it found out the group advocated Holocaust denial. It's telling that the University does not see fit to cancel hosting an event for a group led by the Discovery Institute, which is devoted to denial of serious academic research. It's rather disgusting actually...
