Staff Sergeant Alva need not to have worried. Marines will always judge a fellow Marine because he made it through Boot Camp and on his ability to perform as any Marine should. The fact that no one knew means he was not gay but was a homosexual male ... a gay is that pathetic swishy creature who thinks he is a woman. A gay would never have been accepted. As a heterosexual male I don't believe my sex life is anyone's business (I don't kiss and tell).
I may have had friends who were homosexuals and I probably served with some. The fact that you can't tell by looking means they carry themselves as men and can be accepted as men ... what their private lives are is their business. I have never judged any of my heterosexual friends because of who they have a private life with and I would never disavow friendship with a friend if I learned he was homosexual. The vast majority of Homosexuals live a private sex life much as do the majority of Heterosexuals. I believe that few Homosexuals would make a move on anyone they know to be Heterosexual and that's important. That gay creature might make such a move and that's when the trouble starts, rightly so. The males or females who attempt to be something they are not are despicable.
