I was listening to NPR this morning, and they had a little thing on about how some (and I emphasize some) military chaplains are resisting the repeal of DADT. One of the chaplains complained that he shouldn't have to "choose between his religion and his job."
Well, yes, you do have to choose. Unlike the gay and lesbian military personnel you are currently supposed to serve, you get to choose. Having that choice is a privilege.
If you can't serve the people the military needs you to serve, then choose not to enlist or re-enlist.
