One of the biggest lies spread by the opponents of marriage equality is that once its legal, churches will be forced to have and bless gay weddings.
This is false.
The First Amendment already protects religious groups from accepting things they don't want, even if the state has already accepted it. Separation of church and state, my friend.
And several of these proposed bills have explicit sections saying that religious groups - churches, denominations, synagogues, temples - will not be required to sanction gay weddings in any way.
This has always been the movement's credo. We want marriage equality as sanctioned by government, not by church. The government already sanctions different-sex marriage. Churches will do what they want, as before.
When people realize this non-threat, they get more supportive:
Light lines represent initial support for marriage
Dark lines represent support when people are assured that their religious group won't be required to copy state law.
