I think the larger issue is our culture around alcohol. I see the campus police reports for the college I work for and most reported sexual assaults occur in the residence halls.
I’m honestly not trying to defend fraternities, but my experience (admittedly as a guy) is that there are good and bad fraternities. I was a non-drinking brother at a fraternity 30 years ago. I staffed the root beer supply for non-drinkers attending our parties. We also had a rotating designated driver. We did not tolerate any behavior like that nor did we trust brothers who had been drinking to do the right thing. We were probably unusual, but not unique.
That said, I knew at least two frat houses on campus that I wouldn’t have allowed my worst enemy to visit, and we told everyone we knew about them. Most people knew their reputation, but their parties were still popular.
