In my early twenties, before I converted (I was rather pagan back then). I kept company mostly with the gay community. There are a few things about gays that I can state with some authority (at least in my city).
In general, an exclusively homosexual person is extremely rare. By far the majority of homosexuals have relations with both sexes, and do so with reckless abandon. This is probably more prevalent amongst men in the gay community than it is with women. Gay women tend to be a little less promiscuous than gay men. There are a few rare exceptions out there where you think... this person is like a woman trapped in a man's body, or vice versa. But this is rare, and the men especially who are like this tend to be shunned by their own communities, because when a gay man wants to have a "boyfriend" he wants him to be a man, not a woman. Another thing about the extreme, who I think of as transexuals, is that they are very mentally off kilter. They are often extremely self-destructive, and suffer from delusions. I think it's like some form of schizophrenia almost.
Basically my take on homosexuals is that they either suffer from an obsession with sexual gratification, having to push the envelope in order to gain fleeting pleasure from their increasingly perverse behaviors. Or, in the rare case, they are very sick in the head, and suffer a form of delusion.
I think it's appropriate that the church should teach that we have charity and compassion for these people. But nowhere is it suggested that their behavior is fine. Their behavior needs correction. In the end, they keep having broken families, and broken lives. No matter what their politically correct nonsense tells us, they will not find peace with their present association. Besides, the church holds to the moral precept that any relations outside of marriage are intrinsically wrong, and a very grave mortal sin. How can the kind of promiscuous activity that homosexuals revel in ever be condoned by the church?
