both, bullying and hazing, (not synonyms as DaGuru said) have their place.
yes, I am a straight white male between the ages of 18-24, probably the second-highest demographic for this type of shit...but both of them have positive implications as well.
bullying, especially in 7th-9th grade serves its purpose to prepare people for the mean cold world ahead, granted, I wasn't bullied to the point I wanted to kill myself, it was just normal middle school shenanigans, but now I'm older, its definitely prepared me for life. there is definitely a line that can't be crossed, but in its current state (no-tolerance) its doing more harm than good for high-functioning normal people.
hazing is different, it has its place and its limits. in the story in OP, it sounds like the limits were definitely exceeded. in PA, hazing is defined as-"any action or situation which recklessly or intentionally endangers the mental or physical health or safety of a student or which fully destroys or removes public or private property for the purpose of initiation or admission into or affiliation with, or as a condition for continued membership, in any group or organization, the willingness of an individual to participate in such activity notwithstanding.”
I think hazing fortifies the brotherhood of these organizations, so long as it doesn't get out of hand.
I think the organizations should be up-front about what it involves, so pledges can decide if they want to or not, and also have a bail out clause as well.
I was trying to find the whistle-blower list of hazing they have here at my school, but I can't find it. there was some stupid shit on there I remember.
I think the whole hazing/bullying movement is people who couldn't handle it in school, and are trying to figuratively get back at "butch" or "gary" or whoever bullied them in high school, and that makes them feel all big and powerful inside.
