Let's take a closer look at the 'Tower of Babel' story. This biblical story tells us that all the people of the world spoke ONE language prior to the hubris of the construction of the Tower of Babel. God saw this hubris and ordered the scattering of people and gave them all separate languages.
God punished people by giving them separate languages and scattering them across the world and making them peoples. To allow the intermarriage of peoples is against God's law. To allow people with wrong skin color in a white school is against God's law. Godly conservatives know to put God above political correctness. The point is the slave holding Founding Fathers never considered themselves to be racists.
