Hence why the idea of "rights" is subjective to the whims of man, not God or gods.
I wouldn't say "subjective", nor would I say "whims". I do think rights are based on moral truths, but I think our conception of those moral truths become clearer as we mature morally. You've often argued something to the effect that the founders who owned slaves acted immorally. And I've argued that we can't apply today's moral standards to yesterday's behaviors. Yes. What they did was objectively immoral, as it broke the inherent right of people to pursue life and liberty. It came to a head when more and more people began to understand that the right to liberty extends at least to all humans, not just the ones with light skin. That was a case of right overcoming might. Moral truths are like discoveries. We learn more about them as we study them and incorporate them into our worldview.
