I think the primary determining factor as to whether or not a school and its community is its location. For example, chances are that TUCOM and CCOM will be more "accepting" than KCOM and PCSOM. The reason is that San Fransisco and Chicago are less conservative and religious than Kirksville and Pikeville plus they have a greater population of gay citizens in their communities, thus leading to greater acceptance. Whether or not this holds true for the surrounding community only, the student body only, or both, is difficult to say.
Another thing to consider. Since you are interested in osteopathic schools, remember that lots of time will be devoted to hands-on contact with other students in manipulation lab. This could create serious problems with people who are not comfortable with homosexuality. Unfair, stupid, ridiculous, yes, but unfortunately, that's the world we live in. This of course is probably not much of a "problem" in allopathic schools but could be a potential one in osteopathic schools. So, while your sexuality is a part of who you are and you should be able to reveal this about yourself, you might want to think about how open you want to be not because you don't want to make others uncomfortable but because it would be better for yourself.
