Fun fact: The vast majority of our "rights" are natural. The question is who protects them?
A marginalized group does not receive human rights, they are stripped of them. The removal of your birthrights should be violently opposed as soon as possible.
I agree! But we can hardly call that natural. That's a carefully cultivated world and society that ensures fair and equal distribution to everyone according to their need - something that has never existed. Even under primitive communism the gens/tribe might be motivated to oppress outsiders because nature itself imposes scarcity or disease or disaster on them.
In order to ensure all rights for all people, we must also conquer nature. It just doesn't make sense to give credit to nature for our rights, when we have always had to fight against nature to have the right to live.
