I recall some huge amounts of anti-greek activities during my third year of college...there were signs put up all over the place proclaiming "fuck frats! Do you really need to pay for friends?"
I had nothing to do with those but was one of a large mass of humanity who silently agreed...
The Residence Life office or whoever responded to this by setting up dorm floor meetings where we were lectured by some frat rat or another on why they were so cool and shit. On my floor, most of us walked out during the harangue.
As far as I'm concerned, it's something to do for the spoonfed snobbish kids who think they aren't already spending enough of mommy and daddy's money.
I wanted to get involved in leadership and organization so I participated in student government and several para-academic clubs. Didn't spend a dime, and didn't ever wake up in Detox.
