Well, I can "view" my left arm as my right leg. Don't make it so. Male on male sex in any form is homosexuality, wether these prison queers admit it on not.
I agree with your statement. Certainly anal-sex between two men is a homosexual act. I just don't see these perps as homos in the typical limp-wristed sense. They are more sadistic, looking for a way to inflict an unimaginal form of abuse on someone physically smaller than them for no better reason than to exert power and dominance in a situation where they are otherwise powerless. I would doubt that outside of prison, these people exhibit any homosexual tendencies whatsoever.
