PNM slidehow leaked from frat I was rushing...advice?

[spat1]

I'm rushing a year later than normal for my school.

One of the current brothers borrowed my laptop last night while I was out of the room (he had my permission). He logged out of his email, but apparently didn't realize he had a nice powerpoint open -- PNMs.ppt

I had no idea such a thing even existed -- they have an exhaustive list of every potential new member. One or more slides per person-- complete with their facebook profile photo, descriptions of them from brothers (signed with a number not a name), and a LOT of really hateful things for the people they don't like/don't want in. Even some weird things like comments on penis size (how the hell do they know anyway?)

Nothing negative was said about me-- in fact it seems they want to give me a bid. However, it was really disheartening to read some of the horrifically cruel things that they said about some other students I know.

The slideshow also included "proposed" hazing activities...things way more hardcore (and gay as fuck) than I would have imagined.

As you might suspect, I'm now having second thoughts about this process. People that I consider my friends have been writing these horrible things and their pledging is clearly far nastier than I ever would have believed.

What do?
