Its not like there are not gay people in the military already. I know of plenty of gay people who served the Armed Forces well. I thought this country was supposed to stand for freedom anyway. (You know, like freedom of speech)
People who are against rights for gay people hate the American ideals of freedom and equality.
And since there are very qualified gay people in the military who are needed to accomplish our goals abroad, people who want to weaken the military by taking these people out of service, obviously hate the military.
