Your wrong on this big time. All of my friends in the military are getting out. Just about every one of them. If you think a very small number of the whole (homos) are going to replace that you should realize your #s and beliefs are naive at best.
You should also believe that men should be able to live and shower with women in the military as well. Again, you don't realize the consequences of homos in the military. Normal straight guys will be hit on.
Also the idea that lifestyle means nothing in relation to culture forgets that every major civilization which accepted homosexuality had a short life span after the fact. It wasn't homosexuality that was the cause, that would be short-sighted, but the moral decadence that is accompanied by it.
As Aristotle wisely said, "Tolerance is the last virtue of a dying civilization."
