Off the top of my head... there's Big Gay Weekend/Drag Ball (an (awesome) annual event), Rainbow Alliance (LGBTQ group), Advocates (gay/straight alliance), speakers on campus (B. D. Wong was there one year), and "safe-zone training" that I think everyone in the administration gets, as well as RAs and other students interested. There's a newsletter published... monthly? Semesterly? called "Out and About" (more here:
Colgate: LGBTQ ) I remember something about Colgate being ranked as among the more gay-friendly schools in some publication...
In my experience, people of any orientation were accepted easily, but that may not be true among all groups (mens varsity sports teams come to mind...). Still, there are openly gay students that are at the top of student government and the 2007 winner of the 1819 award (which is a HUGE, huge deal) was out and really involved on campus with LGBTQ issues. Though Colgate has a reputation for being a bit WASPy, there's plenty of students of different backgrounds - and we could always use more!
