Nehemiah refused the help of Sanballat and Tobiah because they hated the Lord God of Israel . . . Sodomites hate God or they would not be practicing their deviant behavior - I do not need thier help, let them vote for their own kind.
Helllooooo? Are you kidding me?? Your sins are just peachy, and you are a good Christian, but if anyone's sins are abhorrent to you, then they "hate G-d"?
I've got news for you: G-d wants each of us to focus on our OWN sins. Yours (and mine) are NO BETTER than a gay man's sins.
