You just proved my point. He thought he got to decide based on "who is contributing enough," and you have said that you think you get to recognize rights based on your utilitarian judgment that, and I quote: "equal rights maximizes your society’s output, because you have more people in a position to contribute to the full extent of their ability."
Same premise: your opinion about what is best for you, and/or for "society."
Without God, and the in-born morality that all of us recognize in our conscience, in the equation, all that is left is your subjective, impetuous opinion. Or the opinion of Malthus. or Marx. Or whomever.
If it ain't God-centered, it will be self-centered. And, as all human history has shown, disastrous in the end.
No VASTLY different premises, which I have explained to you, multiple times. Sorry but at this point you are simply being willfully ignorant to erect strawmen. Thus there’s no reason to continue. Bye.
