I agree with everything you've said, D. The only excuse I can think of is keeping homosexuals out, or at least silent about their orientation, is for their safety in combat situations. Not that I agree with it, but I thought back to what my dad told me.

We were talking about inaccuracies in Vietnam War movies. He said there werent a lot of mixed-race units, in fact during his two and one half tours, he had only one black man in his unit. The reason is that giving a gun to a bunch of potentially racist men and then sending them into a combat situation where it's easy to shoot someone you hate and blame it on enemy fire isnt a good idea.

Now, its not the smartest thing, and it's definitly not the only reason, but it could be a factor and I thought I'd put my two cents in, because it was a reality during that time for blacks, and could be a reality during this time for gays.

Edit: And the gay thing doesnt usually work to get you out or keep you out. They'll blatantly ignore it, most of the time. I watched a kid go up to a drill sergeant, say he was gay... and the sgt. just laughed it off.
