I went to a private college and ALL colleges in the United States, with the exception of Hillsdale and Grove City Colleges are direct and/or indirect recipients of federal funding and are held responsible for violating what could be construed as an infringement on civil liberties.
Not that simple. Colleges are not designed to produce a "Burning Man" no-rules environment.
All liberties are sustained by group commitments: I agree not to kill you if you agree not to kill me.
College communities admit groups of people (not just individuals) on conditions, one of which is that the group agrees to study together. Medieval academics wore guild gowns to signal family membership and pride in their teams. Sounds like the alphas at Morehouse are deciding how to express themselves as a group through academic dress. No surprises there.
My recommendation is to restore medieval guild gowns at Moorehouse, and let students run around naked underneath them if they want to. That would be fun. It would make it much easier to jerk off and flash during boring lectures, or get the quick relief during breaks. The free balling would be fantastic.
