More and bigger, maybe not, but not disappearing either.
I was also in a fraternity, one that (even at the chapter level at that time anyway) did not believe in hazing of any form. Hazing should be deservedly relegated to the same status as bullying. It's all about leadership though. It only takes one or two bad apples to ruin the whole bushel.
I know fraternities have a reputation for hazing members going way back. Heck, it took me forever to convince my wife that there wasn't hazing that I just wouldn't tell her about. As I mentioned before, I don't know all the answers, but I feel that getting the Greeks to be more active on campus would help to improve attendance. Jmo
