Stop offering tax breaks, healthcare, and other perks of being heterosexual spouses. That is the issue.

If you wan't to protect the sanctity of marriage, go to church. If a gay couple wants to get married, don't go to their church. Problem solved. Too bad people always want to judge and impose their values on others. It is more funny when so called "Christians" do. What did Jesus say about judging people? O ya, that's right....Don't do it. It is not your place.
