And again, I reiterate what I said earlier. Where do rights come from?
If they come from God, well, the religions practiced by virtually all people worldwide have consistently said throughout their history that such a marriage is not a marriage.
Religions are human-made institutions and thus, unlike God, are fallible. Your confusion of human-made institutions with God is the epitome of hubris. If you believe believe basic human rights came from God then why do you think humans running religions have a right to take them away?
This was the basic point the Founding Fathers were making when using the terms "Nature's God" and "their Creator" in the Declaration of Independence:
When in the Course of human events, it becomes necessary for one people to dissolve the political bands which have connected them with another, and to assume among the powers of the earth, the separate and equal station to which the Laws of Nature and of Nature's God entitle them, a decent respect to the opinions of mankind requires that they should declare the causes which impel them to the separation.
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
So what you are saying, that human-made religious institutions can take away inalienable rights bestowed by a Creator or by Nature's God, is the exact opposite of what the Founding Fathers said in their Declaration if Independence.
