Just because Jesus affirmed sexual prototypes in first-century marriage rituals in Matthew 19 does not necessarily mean that he simultaneously denied the existence of the continuum that is human sexuality. How else to explain hermaphrodites? After all, they existed during Jesus' time and the Son of God would most certainly have known about their existence.

As for Mark 10, Jesus was discussing divorce, including the fact that they who divorce commit the sin of adultery, a sin which Leviticus, every homophobe's favorite book of the Bible, says is deserving of the death penalty. Funny how you never hear about that part. Mind you, Jesus never said a single word about homosexuality, yet you cite as your "proof" of Jesus' homophobia his admonition against heterosexual divorce. I'm not sure my college logic instructor would give you a very good grade on that construct.
