From Eat Your Heart Out, Ho Chi Minh: Or Things You Won’t Learn at Yale, by Tony Thompson (BookSurge, 2012), Kindle pp. 190-191:
The visual difference from the pre-war Yale of 1963 was more in the variety of clothing and in the variety of long hair-styles, and in how the beholder was supposed to respond, rather than in the amount of facial hair—especially in the desired response, these guys didn’t want to look interchangeable, like infantry soldiers or the Kingston Trio. They wanted to tell you something when you looked at them.
So you had the common “I love the workers” style or the basic Bob Dylan clone—the Pendleton-shirted, anorexic lumberjack look. And, to show identity with the people—but with the Russian people—you had the Fiddler on the Roof or Russian peasant type.
Many students were angry—really, really angry—so you had the never-smiling, stubble-faced, T-shirt, and torn jeans “yes, I sleep in my clothes; fuck you” appearance.
Some kids were sensitive—they felt the cruel pain of life and war so terribly intensely—so they wore tattered Sears work clothes and sported a stick-thin, crazy-eyed, greasy-filthy look that proclaimed: “I have suffered a nervous breakdown over this terrible world; I weep for the little people so much; please share the love.”
But the preppy, Shetland sweater and chinos look was still popular; I didn’t have to ditch my clothes….
What you didn’t have, beneath the surface, was much of a change in the social background of the students. A smaller percent came from private schools. There were more Jewish guys from public schools. But, public school or private school, Yale in 1966 was still overwhelmingly a place for white, middleclass, suburban boys.
Compared with the army, blacks were still almost invisible at Yale in 1966, despite the brand-new, fervid, vocal desire of so many at Yale to raise, liberate, or merely improve the lot of black Americans.
That the army was already doing these things for hundreds of thousands of typical young blacks was simply beyond the comprehension of these white suburban Yalies—who didn’t know any black Americans.
It would be many years before Yale had a sizable, representative cross-section of intelligent black American students, as opposed to a small, self-segregated cadre of handpicked, cosseted, and atypical blacks.
Whites and blacks also mingled far less at Yale than they had in the army. But at least they didn’t fight with each other.
In contrast with the army, I witnessed no overtly gay behavior back at Yale. Probably I didn’t know where to look.
