Sweetie, I hate to break it to you but you and your posse of homophobic fundamentalist evangelicals don't own the Christian church. You don't have the authority to speak on behalf of the UU, United church, Catholics, Anglicans, Protestants, etc. You and your church are a tiny minority (although noisy beyond your numbers) and are quite out of sync with mainstream Christianity.
Mainstream Christians, if they oppose same sex marriage (and there is no guarantee), oppose it because they believe the union of male and female is sacred, not because - like you and your church - they think homosexuals are all evil, unrepentant sinners choosing lives that are offensive to god, who will burn forever in hell.
Because of that, most Christian churches have come to terms with the reality of homosexuality. Some are marrying gay couples in church, some have openly gay ministers, some have a tradition like confession so that homosexuals can give celibacy their best shot but be forgiven when they fail. (Pretty much inevitable, since almost everybody who has a sex drive to begin with fails at celibacy.) So you, my dear, are the anomaly. You're the vocal minority shoving your beliefs down everybody else's throat.
So what if your church doesn't want homosexuals? They'll just go to the UU church up the street, where nobody wants people like you.
