Maybe I have my head up my ass since I am apparently a cisgender white female of the truest sort, but I want to tell you that even out here at OkSU, you would be treated well by the students and faculty, and that you would be okay out and about in Stillwater. But honestly, I don't know. I know I would have gone to bat for you - I'm sure someone would - but it might be much more of a struggle than I would like to acknowledge. I do still live in the state - maybe it's a coping mechanism. Pretend that 80% of the people are as open as I am and the other 20%, well, f em. But I bet the true ratio is not so kind.
If people cross OkSU off their list because they are scared of tornados, then crossing it off because you don't want to feel persecuted is definitely legitimate. I just wish it weren't an issue, here or anywhere.
Good luck!
FWIW, we do have several gay faculty, mostly females. It's not exactly broadcast, but it's known, and no one seems to care. Being trans may present more problems than being gay, though, as I'm sure you know. *shrug/sigh*
