Miriam, the sister of Moses, had a problem with his marriage to a Nubian(black) woman. She spoke out against Moses and God punished her with leprosy.
The word of almighty God warns man against racial prejudice but man insists on hating his brother for the color of his skin!
Therefore there is a curse on those who hate on the basis of race!
I hate any kind of racism!
Every man, no matter the color of his skin, is my brother man!
