scripps doesn't keep a record of the percentage of sexual orientations on campus, so i can't really help you there. however, the atmosphere is definitely gay-friendly. there are a handful of clubs on campus dedicated to awareness and unity of gays/lesbians/transgendered people. there is a queer resource center for the 5c's, too. i'm not much help on this topic, though; the best way to find out would probably be to visit the schools and see for yourself.
