From the Contra Costa Times:

A number of Stanford University faculty members are protesting the Hoover Institution’s appointment of former Defense Secretary Donald Rumsfeld as a visiting fellow.
The conservative public policy think tank is not formally connected to Stanford, but it is located on campus. That rankles some of the university’s scholars. Evidently, they cannot bear to share space with a facility that welcomes people who do not share whatever happens to be the politically correct view of the world in the Stanford faculty lounge.
Leading the protest against Rumsfeld’s appointment is professor emeritus of psychology Philip Zimbardo. He said Hoover “can have any fascist they want there, and they do … but this seems to be egregious.” What’s egregious is Zimbardo’s name calling and intolerance.
However unpopular Rumsfeld is, and there is good cause for it, he held a key position in government and should not be silenced. Scholars such as Zimbardo do a disservice to academic freedom when they oppose airing controversial views in an open forum.
