That's a very good argument for why gay marriage should be allowed, and IIRC the one that the supreme court followed. That doesn't mean that there aren't still people who would challenge the morality of such.

Morals and legality are different. Marijuana is federally illegal - does that make it immoral to produce/distribute/possess/consume? I would say no, and a large part of the country would say the same. Similarly, I think a ton of people would freak the fuck out if the supreme court legalized marrying prepubescent children - it might now be legal, but that doesn't make it moral.

The moral position that people fighting gay marriage have is that the current caselaw is wrong, and that equal protection shouldn't be interpreted that way.

You keep indicating at some hypothetical argument from morality. Can you just lay it out? First you claimed both sides were relying on a purely moral argument, but you seem to have moved on from that after I gave the constitutional argument for gay marriage. Now you’re arguing there’s a moral argument against gay marriage, but I can’t fathom it. Can you be more specific?

> “Gay people shouldn’t have the same legal rights as straight people” is a moral position? Which commandment is that one?

I've been trying to explain how it's a moral position for some people, in response to this statement of yours. I'm not sure how to make that argument in a way that would be convincing to you, in large part because it's not convincing to me.

And I suppose we may be getting some wires crossed - for a lot of people in the world, there doesn't have to be a justification for a moral belief - or at least not one you would accept. "My religious authority told me" or "my parents told me" might not be as acceptable in the society we live in today, but they've all been extremely successful throughout history.
