The difference is, race isn’t sexual orientation no matter how much the homo community would like to make it. Fact is, homosexuality is a sexual perversion, abnormal.
The military and society finally got over the race issue (and now it’s being used as victim status, that can’t be denied). Race isn’t a choice. Sexual perversion is. There’s a difference.
So's religion. Our society has pretty much gotten over that one, too.
We have managed to have a gender-integrated military, we will figure out how to get along in this area, too. Not every gay or lesbian person is the flaming queer whose loves to show off in the gay pride day parade.
