Well, likely because there aren't any, besides wishful thinking of fairly naive people on FR.
I'd bet money not one of the male soldiers involved in this turns out to be gay or ever had any homosexual activity in his life. Already one is being prosecuted for taking pics of female soldiers at the prison, doesn't sound very gay to me.
Especially given the desire just to write the whole thing off to "gays in the military," it's certainly understandable to simply say the pics of the Iraqis forced into contact with each other nude was a homosexual gratifying a fetish, if you don't think very hard.
But given similar scandals in the US (such as at the sports camp where there were similar hazing type things), in my opinion this isn't gay fantasies taken to the nth degree, it's dominant jock types throwing the nerdy boy's backpack in the girls locker room, or pantsing the new kid and giving him a wedgie, to the nth degree (not saying what happened in Iraq was of a similar level as giving a wedgie, I'm just saying it's the horrible extension of the same desire to humiliate, express dominance, and laugh at a victim, particularly by high school/jock bully types.)
Quoting from the Army report:
“They (detainees) were all naked, a bunch of people from MI, the MP were there that night and the inmates were ordered by SGT Granier and SGT Frederick ordered the guys while questioning them to admit what they did. They made them do strange exercises by sliding on their stomach, jump up and down, throw water on them and made them some wet, called them all kinds of names such as “gays” do they like to make love to guys, then they handcuffed their hands together and their legs with shackles and started to stack them on top of each other by insuring that the bottom guys penis will touch the guy on tops butt.”
That doesn't sound like a couple of gay guys making prisoners do that for sexual gratification, it sounds like a couple of homophobe jock bullies doing it to the prisoners because it was the most humiliating thing they could think of.
I also don't think the presence of women really made much of a difference. I suspect it would have happened without them, only difference is that women wouldn't have appeared in the pics and annoyed the Arabs quite as much as it has.
Donning flame-resistant suit as an awful lot of people find it really convenient to blame it either on women or gays in the military. I really don't think it had anything to do with either. It was just a poor command structure, poor commanders, and enough lowlifes (but fairly run-of-the-mill lowlifes, not anomalous or out of the ordinary) in the wrong place at the wrong time.
