Gays are sick people. I believe the defect in most cases is congenital and genetic. It occurs in nature in certain animal species, but that, of course, is not a justification for it, after all, we are human beings, not animals, and we were given commandments to elevate us from our natural depraved state.
I am tempted to say that the most compassionate thing we can do for a gay person is kill him, and spare him a lifetime of confused and agonizing existence, but who am I to decide who is to live and who is to die? After all, the life of a quadraplegic is just as miserable, yet nobody suggests euthanizing quadraplegics. Plus, there are homosexuals who attempt to brave their condition, get married to women, have children, but later in life give in to their genetic (mis-)programming, because they can't continue pretending anymore, and they may either just leave their family and live alone, or enter an abominable relationship with another man. Do they not deserve credit for at least trying to be normal for a few decades?
It's a complicated issue.
