College students, our nation's best and brightest, often do stupid things, such as spread peanut butter on somebody. A year or so after I left college, one of our fraternities lost their charter for a time. They had a tradition of throwing young men into the river when they pin a girl. One time, they decided to warm the fellow up afterwards by dumping boiling water on him. Yikes.
The young man who was president of the house at the time went on to get a very good job after graduation. And I wondered if his employer knew about the disaster he had overseen. Or did they hire him in part because he was a frat boy?
I have nothing against fraternities and I don't think others should exhibit a bias against them. But a bias for them when hiring might also be a mistake.
