DePaul math prof Jonathan Cohen offers a detailed report of how the administration of his own school tried to blame campus conservatives for the appearance of racist and anti-Semitic graffiti–without a shred of evidence (of course):
What has occurred has been another example of political correctness run amok at DePaul. A small group of students engaged in a relatively innocuous public protest of affirmative action and as a result they were investigated for a possible case of harassment, had their organization censured and penalized by the university, were tricked into being subjected to a two hour public bashing at the hands of several faculty members and in front of about a hundred jeering students, were publicly scolded for the bake sale by the university president in an email to every member of the DePaul community, were the victims of a crude attempt to falsely brand them as the perpetrators of a nasty incident of racist graffiti and when they were cleared of this charge the school administration, knowing that this was a hoax, suggested to the media that their bake sale had contributed to the atmosphere that led to the graffiti.
