I think Balsalm was referring to this point within the article
When they get out, these men may never "identify" as active members of the gay community. But they may choose to go on seeking sexual and emotional satisfaction with other men, and they may do this in covert, even violent ways.
The article reflects that the same notion as the Kinsey Scale. It's not black/white - straight/gay but the dogmatic religious approach has unfortunately polarised the argument when reality reveals human sexuality as a broad spectrum, or fluid.
