DavidTheWinThat just goes to show how susceptible people are to brainwashing. People used religion (the thing about Noah's black son seeing him naked whilst asleep) among other non-religious reasons (being under the idea that black people were physically inferior) to justify slavery and racism towards black people.
I have never read anywhere in the Bible about Noah having a black son who was seen as inferior. If someone actually used this as an excuse to justify slavery, then it is completely unfounded in the Christian faith. I would chalk that up to an individual trying to find some excuse to justify something that he knew to be wrong, and eventually everyone else just started using that same excuse. Everyone knows that slavery is wrong, however, slavery was a great way to make money back then. For a small cost, you could have free labor for literally generations.
