You are right they will argue on political, sociological, and other grounds also.
It would be interesting to know exactly how many gay men and women are in the military as of now including bisexuals, men who have anal sex with women, multiple sex partners,sex with prostitutes etc. As these would all be considered deviant sexual practices unbecoming of the military service. Now how many soldiers do you suppose would be left to fight the war? No argument here just wondering who would be left in our military, maybe Billy Bob, but then he got his sister knocked up when she was 13 so that rules him out. lol
