Our Founding Fathers were great (better than most) but flawed men of the time. I despise racism whether it is black on white, or white on black. I prefer the Bible’s teachings on the matter.
Galatians 3:28
There is neither Jew nor Gentile, neither slave nor free, nor is there male and female, for you are all one in Christ Jesus.
