Having served with several people who were gay, it is greatly "prejudicial to good order and discipline". How long until the first guy is offended in the shower cuz his squadmate is openly eye-humping him? How long until that squadmate gets his ass beat? How many fire teams will be disrupted? How many guys won't want to practice the fireman's carry, neck drag, etc., because they know their gay squadmate has the hots for them? How many commander's/1sg's will have time taken up by accomodating the homosexual troops (moving them to different barracks, platoons, etc.) when they could be planning or conducting training that will keep troops alive?
