There are consequences to waiting. Couples are denied their rights, which has ramifications from child custody to driver licenses to death certificates. Look at what the status quo means: Gay couples separated in hospitals. Losing their life savings when one passes away. Having a marriage license revoked when they cross state lines.
You don't like gay marriage? Fine. Don't get gay-married. But if you want to have a business and operate in the public sphere, then you've got to treat all your fellow citizens equally. Even better would be to treat each of them as you would wish to be treated. That's a rule that should sound familiar to someone as knowledgeable of the New Testament as Bobby Jindal.
