Jesus would love and accept gay people, because they were born that way.
What you've quoted from the Bible and concluded would be ok if there wasn't specific mention in the Bible against homosexuality. Working from memory only, I believe Deuteronomy says commiting the act of homosexuality should be punished by stoning.
And if I'm not mistaken, Jesus says to continue to obey all of his Father's laws.
So if Jesus was obeying his Father's laws, he would have to condemn homosexuals to death by stoning. I would imagine the idea of homosexuals getting married would be unacceptable to him as well. Jesus would see homosexuality as the racist of the South saw interracial unions.
