...that you have some sort of nature vs. nurture argument to be able to justify your position, but could you substitute "black" or "Jew" for "gay" and be happy with your assessment?  "Our military is doing a good job, and they don't want any blacks tap dancing or Jews counting money in the foxholes next to them.  That would be an obvious negative effect on morale (to ignorant people like yourself.)  If blacks want to organize a 20-minute-late military gold tooth pageant or Jews want to organize a briscuit and gelfilte fish dinner, I'm sure they would do a marvelous job, cracker/mensch."

I know--the argument is that sexuality is interior (unlike race) and if no one mentions it, no one will know.  That doesn't cover you from the religious part of my example, but regardless, it is bullsh*t anyway.  I have many friends in the military.  It is largely a bunch of 20-year-old guys killing time for months on end in close quarters.  You don't think (hetero) sex is brought up and discussed 50 times a week?  You don't think the guys talk about female celebrities and girlfriends and fellow female soldiers?  And female CIVILIANS in Iraq?  You don't think that most men can determine who in their unit is almost surely gay within a week without those soliders "putting the make on them in the heat of combat?"

This isn't Will and Grace, Ken.  We need all of the recruits we can get.  Morale drops a lot more from the fatigue of not having enough men than it does from proximity to something slightly out of a few bigots' comfort zones.
