You are talking about American prisons, aren't you? Everyone knows all Beta ST males are latent homosexuals, the ones that populate outlaw biker gangs, and other 'brotherhoods' such as the Nazi Sturm Abteilung. Except those that already had their coming out, of course.
What am I saying? I'm so fucking biased in my generalizations. Fortunately, so are outlaw bikers. Why else would anyone without an official function wear a uniform? To signal their preference for anal sex, of course!
