Wolfpackmarine, I know a couple of prior enlisted guys who got appointments to the Naval Academy so they had to do the whole plebe year thing even though they'd been in the navy or marines already for a couple of years.
You'd think they'd really resent being yelled at and ordered around by guys younger than them and certainly without as much experience. But, to a man, they said that it was easy because they'd already been exposed to pressure situations so having to recite the day's menu or chopping corners were really no big deal. Plus, they were mature enough to know that it's not something to be taken personally.
Obviously, being a plebe and being a pledge isn't EXACTLY the same thing but I think there are enough similarities that you could draw a comparison.
I think you would have a lot to offer a fraternity and you should give it a shot
