IMO, I don't give a crap what a soldier's sexual orientation is as long as they keep it to themselves.
I know that personally, I find beastiality abhorent. If a soldier was into that and didn't tell anyone there are no repercussions. If however, I live in a barracks and have to be in the same room with some guy who has a date with a goat every night (particularly if he brings his "date" to the same room we both live in) there is going to be one dead goat as a minimum.
Truth is, I think Gunny has the gist of it. There are gays serving currently and gays have served in the past. The ones we hear about are the ones who want ot protest and "flaunt" thier sexuality. I dont like it when soldiers talk about heterosexual exploits (the "epic stud" stories) and I dont like it when gays talk about homosexual exploits.
Further, RGS also has a point. Living quarters for soldiers are set up the way they are for a reason (having a whole lot to do with good order and discipline of the unit....an essential for an effective fighting force). we are not talking about a college campus with a bunch of students here.
