OTOH, there is a certain amount of prurient charm in the idea of sorority sisters ritually spanking each other, so maybe I should cut them some slack.
Group think, peer pressure, and the “need to fit in” is the only explanation I can think of.
Sad to say but my experience was that black fraternities and sororities were not covered under Panhel/IFC-at least not at my college.
We would get nailed for having a rush event at a restaurant that happened to have beer on the menu while black pledges walking around school with fresh branded arms (done with coat hangars heated on a stove) would be ignored by the admin.
