A comment from a Boston.com post about legalizing gay marriage:
Then what a church chooses to recognize as marriage is entirely their own business. They can say, 'no, we will not honor gay marriage.' And while that might be regrettable, at least then their refusal does not have any bearing on the nice gay couple down the street having the right to pay taxes jointly or have joint medical coverage. Which is, in the end, what most of them I know want... the ability to be recognized as a single family unit under the law.
