It strikes me that the original poster is throwing out a challenge and making an issue out his sexuality already. The signs are definitely there that he will continue to do that when, and if, he makes it through the system.
All it will do will bring grief on his head - either intentional or unintentional.
Keep your urgings to yourself. Eventually people will suss your situation out but by that time they will have, hopefully, reached the conclusion that you're not a bad bloke and what you do is your own affair.
However.....if you really, really want to push it into peoples faces then I sincerely hope that your IOT flt cdr will start writing up your "chop" sheet from day one after the initial interview where you declare your sexuality and challenge him/her to accept you warts and all. That's what I would have done when I was there.
