You're probably not going to like what I'm about to say, but after reading all of your stats and your background, it seems to me that your best bet would be to not mention that you're trans. At all. You seem more than qualified. I know you are proud of who you are, but the one common denominator I've noticed is you being trans. Most likely, they can't give you a truthful answer, because if they did, all hell would break loose for them given the growing support in the US for the LGBT community. If you don't want to hide that, that's fine. But you're applying for the 4th time, and like you said, insanity is doing the same thing over and over again and expecting a different result. I'm not trying to start an argument here. I'm just staying my observation of your situation. Just my two cents.
