In defense of all the PNM's out there, I really wouldn't worry about some of 'us' asking those kind of questions. At least, the pnm's who have been around at least a year scoping out their choices on campus and seeing which one is right for them, not just the fact of gaining some letters. (Especially the slapping question, I may just ask that one to my 'favorite' sorority, lol)
Also, I still do not believe some of the 'hazing' acts as hazing. It's a bunch of BS. If I join a sorority, I want to EARN my letters, just like the actives did when they were pledging. Heck, I have four older biological sisters, and back in the day the things they did to me would be considered hazing...much worse than what any GLO would wanna do!
Well, those are my worthless 2 cents of randomness.
