While I think you are on the right track, your theology is a bit flawed. I agree that Jesus would have readily "accepted" gay people, in the sense that he would have shown them love. He would not, however, have accepted their behavior. He would have openly and honestly condemned it as a sin. Your implication that all Christians should sell "all you have" also misinterprets the message. It is not a sin to be rich or possess worldly goods, but it is a sin if the love of these things is stronger than one's love of God. There a many very wealthy, very devout, Christians. But you are correct in that there are no levels of sin. Greed is a sin on the exact same "level" as homosexuality.
