One of the ways you earn and fight for those rights is by not claiming they don’t exist. There are already enough people in the world who think you don’t deserve those rights. Best to keep the goal posts far away and convince as many others as you can that that’s where they belong.

Yes, any rights exist because someone earn it or fight for it.

Its not just given from god or something.

And yet tribes and nations that recognize and protect inalienable rights are consistently able to defeat those that assume the strong should have power over the weak.

The reason being that individuals living in societies with inalienable rights feel they have more worth fighting for, and they are more industrious and able to build robust trust networks.

None of that is subjective, it's all how the universe works, so, yes, you could plausibly attribute it to God or any kind of creator.

The strong does always have power over the weak. The right that exist right now is because someone powerful enough to fight for it and maintain it, otherwise those right doesn't exist.

Rights are subjective, meaning it depends on the particular society, even it may have different meaning to everyone. Example: The rights for woman in Afghanistan and USA are different.

But people will reliably fight for it, that's an objective fact.

Agree, some people will fight for it, some people will fight againts it.
