I don’t think anyone in an academic institution would be surprised to hear that leftist/multiculturalists are an organized, imminent, and active threat to free speech in higher education. IUPUI’s discipline (without a hearing) against a student for reading Notre Dame v. The Klan is an extreme example of this trend (h/t Weekly Standard):
The IUPUI AAO seems to have been renamed the IUPUI OEO, but unfortunately it appears to still exist in some form. More on this scandal is available from Reason.
I would be interested in knowing more about this case. In particular, the allegation that the instigator of this scandal is now the Assistant Director of IUPUI OEO is disturbing, to say the least.
