Congress hates gays cause they want to be the only people ****ing you in the arse. 
But what about hawt girl-on-girl action? 

I'll personally note that I don't approve of the behavior in question here, but I will concede to the views of actual servicemen like Nuclear here when it comes to fellow brothers and sisters in arms. As someone who was actively pursueing attaining a career in the Air Force for about two years, what I really wouldn't want to see in a military environment would include notably apparent sexual behavior which is generally disproved of. However, what individuals do on their own time out of uniform is up to them, and relieving qualified personnel from their positions due to activites which, when within reason, should not damage a military organization internally or externally, is irrefutably stupid.
Ah, lest I forget... Shame, Mongoose,
SHAME.
