There's a long list of sins that keep one out of the Kingdom of God and homosexuality is one of them.
Are lying and calling people idiots on that list? I know you say that you are giving what you get on these forums, but didn't Jesus say to move beyond those types of petty grievances? Turn the other cheek? If you condemn the homosexual for continuing in her sin, but do not turn away from your own anger, pride, avarice, whatever, what does that make you? Are you a good ambassador for Christ or is this all for your own pride?
"You are metaphysicians. You can prove anything by metaphysics; and having done so, every metaphysician can prove every other metaphysician wrong--to his own satisfaction. You are anarchists in the realm of thought. And you are mad cosmos-makers. Each of you dwells in a cosmos of his own making, created out of his own fancies and desires. You do not know the real world in which you live, and your thinking has no place in the real world except in so far as it is phenomena of mental aberration." -The Iron Heel by Jack London
