I'm interested in hazing, since my fraternity had a tough process. Pledges had to want to be in the brotherhood, because they would endure hardships.
Hell Weekend, was 3 days of hell. Eating from your Pledge Apple, a whole onion of a string around your neck, as just one example. Hard labor, interrupted sleep, lots of pushups, finishing up dipped in molasses and covered in leaves, a taken 100 miles away to a dirt road in the desert in the winter.
Tradition dictated each pledge be given a dime for a phone call, and a single beer. We walked in single file, wrapped in blankets, to Banning California. Called people that expected call, but not knowing where or when.
When I got to my grandmothers house I was exhausted, looked awful, slept for another day.
Two of the actives from that semester became Superior Court judges, and one probably opposes hazing, now.
We were never forced to drink alcohol. Nobody was injured beyond repair. But it was challenging. I was pledge class president. I don't identify the organization, since secrecy is part of the promise.
SJWs of the present era would cringe in fear. But the prize was entry to a well respected national fraternity, with parties and hot chicks.
