Irrelevant. Things are what they are regardless of what you think, pray, ask, claim, test, or emote. If you truly want to learn about the factual basis of individual rights, there is ample literature for you to look up and read. If you wish to believe or claim that rights are not grounded in the facts of human nature, that's one of your rights.

What the big T Truth is is irrelevant if it can't be proven or measured. Watch:

The fact is that I'm a brain in a jar, therefore you don't really exist and have no rights whatsoever.

For what you say to be fact, and not just your personal belief wrongly presented as such, you first need to prove to me that you really exist.

All this to say, anyone who claims to know the "truth" or "facts" in a discussion about ethics and morals doesn't know what they're talking about.

Ok. So the law of gravity is the law. No matter what I say, right?

The facts subsumed by Newton's laws. Laws themselves are not the facts they are identifications of facts.
