I read the Bell Curve and found it quite interesting. I don't see the correlation to evolution, though.
So it is OK for you to entertain the notion that races are different in intellect, but for someone to think so in 1859 makes them a racist?
If all the races were created by God, then why did it take 6000 years for any believer to notice that slavery is evil, and why, in the entire Bible, did not one prophet take a moment from his busy schedule to say so? Why did it take people like Darwin to notice that slavery is evil?
