Six Presidents of the US since WW2 and 44% of Presidents all time were in fraternities. Once you get past the party animals there are a lot of great qualities learned by being in Greek life.
I know its not for everyone, but go to schools out of the historically liberal Northeast or go to HBCU schools and Greek life is much more structured and embraced.
I fully understand why some people have your opinion, but trust me when I say most fraternities, and of course there are exceptions, but most create the same or less issues for colleges than independent students or sports teams. Remember we are talking about 18 to 22 year old kids away from home for the first time. You don't need to pledge to cause trouble.
