the exact same argument you're making now was used when it was decided to integrate the military.Yeah, this is all nice and everything but the truth is that at this point in time in America, alot of men are not comfortable with being in super close quarters with a black man. Call it racism or whatever you like, but that is just how it is. They shouldn't force legislation like this until America is ready for it. The purpose of the Military is not to provide a platform for social issues- it is for protecting our country.
A big problem with America is that people are so insistent on their "rights" that they selfishly push them to the detriment to others and even themselves. Activists need to wait until people are more comfortable with gays in this country so that they do not help to push through legislation that will undermine the cohesion of soldiers in combat.
the fact is, gays and lesbians are already serving in the army. ending DA/DT doesn't change that, it just allows them to serve without hiding a large portion of their life and removes the risk of retaliatory exposure.
