The causes of homosexuality are disputed, but they seem to be partly innate and partly socialized. One cause is an absent or neglectful father, which may have been the case here. Not enough to say.
Homosexual couples tend to be tolerant of their other's behavior, and NAMBLA is a pretty mainstream homosexual organization, despite pretences to the contrary. So this partner may very well have known about his penchant for little boys yet argued for his release.
The media are aware of all this too, but regretably support it, partly because of the presence of homosexuals in influential positions in academia and the media. The New York Times, for instance, is completely dominated by homosexuals.
Lately I have been listening to gospel singer Donnie McClurkin, his story about being homosexually raped and then living as homosexual for several years is startling. But Praise God, he is living as a witness to people now about the truth in homosexual life style.
Those wedding announcements for gays in NYT are funny (sad but funny. They are like something you would see on Saturday Night Live. So bizarre.
