This is crazy... I can't imagine what would have happened at my high school if students were hazed like what all of you have described... the only thing that could have been categorized as hazing would have been the football "Hell week," which was physical preparation for their games in the middle of August (which in Riverside is usually about 105 degrees). The cheerleaders my freshman year would make the frosh team do stupid stuff, but it wasn't a public humiliation, and they don't even do it anymore.
As for the band... I was in colorguard (ya know, the girls that spin flags and rifles and sabres on the field with the band?) all through high school. Needless to say, I was never hazed, and I never hazed anyone! My sophomore year, we took the new girls in as "Rookies," but we were there to spoil them rotten, make sure they had rides to practice, and watch over them in the horrendous heat... sounds more like a Big/Lil sis program to me...
It bothers me so much to think that hazing goes on in high schools, possibly more often than in colleges! When I'm a teacher in two years, you'd better believe I won't put up with that kind of ****!
