Different venue

I think there is a significant difference between an art show in a public place and an art show in a college. The college is privately owned and should have the right to display or not display mostly whatever they administration dictates. Like most institutions that rely on public perception, it makes sense that they wouldn’t want to alienate a portion of their faculty and student body. So, they end up being very PC. That might not make it logically "justified," but at least it is consistent. Something like Piss Christ can’t really be compared, as it wasn’t displayed in an institution of "higher learning" that had an enrollment to maintain and so couldn’t reasonably be expected to have any real requirements other than getting a permit (or whatever else might be required by the laws of the land).
