Actually, we *should* let gays in the military, just so that issue can resolved once and for all. Here's how it would work...
Openly homosexual men are allowed to joined the military. One of them does what homosexuals always do - he hits on a straight man. The straight man rebuffs his advances. (The myth that gays are only attracted to other gays can be debunked by *any* straight man who has ever had the displeasure of getting hit on by a gay man. It happens all the time.)
Now there is an uncomfortable feeling between the straight man and the homosexual man. Per usual, the two men still share the same shower facility. After the gay man looks at the straight man's arse for the last time, the straight man finally brings up a sexual harassment complaint.
The army has its hands tied. They realize that the straight soldier's complaint is valid and - if not addressed properly - would open the door for male soldiers to peep in female showers without repercussions. Not surprisingly, this type of complaint comes up hundreds, if not thousands, of times. The army realizes that something must be done.
Under pressure to continue to allow gay men to serve, the army begins providing gay soldiers with separate shower facilities - just like they do for women. But - LO - just as you would expect, tension begins to arise between GAY soldiers and one GAY soldier brings a sexual harassment complaint against another one. The army realizes that combat situations do not permit exclusive privacy. They also realize that homosexuals are incompatible with that type of environment. They finally give up on their failed experiment and go back to the way it should be.
We hope... but probably not. It's tougher to take away rights than it is to grant them, so we'd probably just be stuck with a circus sideshow within the army's ranks.
Sigh...
