I'm neither gay, nor in the military, but I do love to see bigots pissed off. These "troop morale" and "unit cohesion" arguments sound an awful lot like the ones used against integrated the troops is all I'm sayin'...
Hypothetically speaking, if the draft were still on, and I got drafted but didn't want to be in the military so I go ahead and declared I was gay (even though I'm not), would they automatically release me from the military?
Not any more. However, in Turkey, you'd have to provide photographic evidence. http://www.foreignpolicy.com/articles/2010/12/03/do_ask_must_tell?page=0,1&hidecomments=yes
