First, I dont think the Rock thing was hazing. To me its one of the public rituals and just b/c something is mandatory doesnt mean its hazing IMHO. If thats the case Initiations could be considered hazing.
HOWEVER, I wasnt hazed and I just like many other GCer's earned our letters and wear them proud.
No offense but if I have to be beat, or some other crap just to join something, its not worth my time and I have less respect for those people who are dishing it out. I will admitt though that somethings that are considered hazing are funny (i.e being tarred with rasberry sauce and feathers and rolling around in it) and I would probably do it just for laughs. Then there is iother hazing that is just stupid (ie walking to class backwards

and not being able to talk to anyone at a party and having to stand against the wall the whole night. I know someone who had to do these things).
