Emergence of the rival shape, which coincided with last week’s annual gay studies conference, has angered the school’s gay and lesbian community. “We see it both as an attack on gays and on this symbol,” says Sheila Allen of the Bisexual, Gay and Lesbian Students Association. Harvard students not allied with either group are tired of their campus being turned into a geometric battleground. The backlash has produced another faction making its mark: SEXs (Students Exasperated by Excessive Symbolism). Their logo: the good old yellow smiley face of the “I’m OK–You’re OK” era. As things shape up at Harvard, however, not everyone is having a nice day.
