My school is, I hope, in the minority. (It's allopathic, but I think these experiences don't fall along MD/DO lines.) We have no support for queer students, except as part of the larger undergrad student body, which fails to address the different issues of the grad and med students. There is open homophobia amongst the students, though on the part of the minority of us. The administration is absolutely silent on the issue, offering no support, recognition, or even thinking about addressing what may well amount to their own tacit approval of harrasing behavior (except that no one's really publicly out, so it's hard to say that there's direct harassment based on orientation). It stinks. However, our counterpart school in Minneapolis is much more supportive in terms of student groups within the med school, administration, and active steps to foster acceptance (or at least tolerance) for each other as we one day must for patients.
I think you need to scope out your school, and classmates. Being out from the beginning may stifle some of the overt stuff, but waiting and seeing if it's worth it can be valuable, too. This latter one is the path I chose, and am glad for it. But I still wish the situation could be vastly different. Med school has enough of its own struggles that I didn't care to add this on top of it -- I hope someone someday will be able to for the sake of future queer students.
