Vito lived with Jeff and Dean their freshman year. One night some upperclassmen dragged Vito back into the room and dumped him, unconscious, on a couch. This was when freshmen began heading for the exits, at first surreptitiously and then less so. I cannot answer these questions. From what I saw and from the accounts of those with much more patience than I, Greek life was conspicuously absent on stage.
Greek life is shared by half of all eligible students and supported by nearly all.
The Dartmouth experience, as defined that Sunday night, is a constant struggle to abandon the dark ages of Dartmouth's tradition and history and transform the campus into some brave, new utopia. We were made to feel good about feeling bad, since everything would get better in due time. Rather it depicted an ideologized view of student life, where fraternities represent intolerance and elitism and the campus resembles one large, loving support group. The presentation generally fit Dartmouth's regnant orthodoxy, and was focused on recasting social life in that spirit, denying the actual state of things. Why freshmen are forced to hear accounts of LSD trips and late-night vomiting is anyone's guess.
