My mother tried to explain how Black and white people should not intermarry because birds don't interbreed.

Birds do interbreed by the way, around 16% or so in the wild, more like 22% overall.

She tried to say Black people are dark-skinned because it is "the mark of Cain." When I pointed out that if that were true, and the story of Noah and the Flood is true, then Cain's descendents would have had to be on the Ark… would have had to be Noah's family.

That did not go over well. 🙄
