As someone who has served alongside soldiers that I know are gay, suspect are gay, or merely call gay, I see no issue with this ruling.
There's more flamboyant homo-eroticism in a highschool football locker room, most of the gays who serve just want to do they're job and go home at the end of the day. I've never had nor seen any issues, personally, that have arisen because someone is gay. They're joes, plain and simple. Everyone's green, and last I checked the Army doesn't allow sex other than missionary, so technically, every last damn one of us is looking at NJP. Regardless of orientation.
And for the guys who have never served, but like to write policy, I bet you all have at least one friend who is gay, and you will never know it. Yet you let them in your home, watch games, and drink beer with them, and have for years. Would you stop being their friend if you found out? Those of you that would, would have no place serving amongst the brave few who are willing to lay down their lives. The others, thanks for being a decent human being.
