Seems to me most trannies are communists and hate the military, i dont really see many trans joining service

No no, think about it. If you're a trans-person who can't afford a $200,000 gender reassignment surgery, and all of a sudden the military is offering surgery for free, wouldn't you join just to get the surgery?

If I were a tranny, I'd join, get the surgery, and quite as soon as possible. $200,000 free dollars.
