But where was their stylish cross in the dirt?

McCain, shortly after his release as a POW in 1973:

Now I don't hate them any more—not these particular guys. I hate and detest the leaders. Some guards would just come in and do their job. When they were told to beat you they would come in and do it. Some seemed to get a big bang out of it. A lot of them were homosexual, although never toward us. Some, who were pretty damned sadistic, seemed to get a big thrill out of the beatings.

How did he know they were "gay" if they weren't gay towards him? Did they say, "Hi, I'm Comrade Cho and I'll be your gay prison guard today." Was it by how they whipped him? Were the "gay" ones in John McCain's mind the ones who enjoyed whipping people?
