Pedophilia in the Bible: this is a porn book

[vulcanlogician]

I have to ask again if you're aware of any provisions in the Bible that would go against slavery as it was practiced in America.

Not aware based on lack of Biblical and/or historical knowledge. Nor do I see how it is relevant to how slavery is generally immoral.

Slavery is objectively immoral.

Oh do tell.

Sure, you can show slavery to be immoral under certain moral systems, but the selection of any particular system as the system is subjective. Atheists used to be good at this.

Wrong. There are two metaethical approaches to objective morality--neither requires a subjective sense. The first is moral naturalism, the idea that moral facts are empirically discernible. Khem seems to like this route. I do not. I am an intuitionist. To me moral facts are self-evident. No subjectivity involved in either view.

As to subjectivity in discerning a proper theory, wrong again. Dude there are logical arguments for/against say hedonism or virtue ethics. Nobody is a virtue ethicist because it "feels right."

But, for me, I tend toward pluralism--ie more than one ethical theory. Kantian deontological ethics, which I see as compelling, emphasizes human dignity and autonomy, so inasmuch as deontological ethics are sound, slavery is objectively wrong.

What do you mean, "Atheists used to be good at this?" It helps if you don't ignore half the post of someone you are arguing with.
