Now I'm justifying beating up homosexuals....
You can't argue this because you have no argument to make that has any bearing on the situation at hand.
No Lives Matter
I have NO DOUBT that if DADT policy is removed and gays are allowed to serve openly the military will be just as strong then as it is today. Yes, there will be some problems with transition, but it isn't impossible.
Unless of course you believe the entire military is just one big bunch of gay hating homophobic people, which I don't believe the military to be.
