Though I agree with the content of your message, I have to point out the Declaration of Independence, though a very sacred document to the USA has no legal bearing. You might as well quote the failed Articles of Confederation that predate our Constitution.

The Declaration affirms Jefferson's belief that those are "God given rights", hardly a constitutional argument. Unfortunately Jefferson didn't feel that way about the slaves he owned, that he appears to have personally bred, at the time he wrote the Declaration.

Let the government sanction gay and straight "unions.". If someone wants more than that they can take it up with their church.
