It took old Chuckie Darwin to give the Western world its race-based chattel slavery alright. /more-sarc — anachronism
I doubt that even Charles Darwin was as Darwinistic as his followers, to state an oxymoron. Theories of evolution were used as an excuse to elide the divine design, not truly as a reason.
Thanks for clearing that up. I never understood the Greek and Roman proclivity for enslaving others until you explained it to me.
