Of course the White Supremacists and KKK hate this movie. They are scared of retribution from enslaving and denigrating human beings for the last 400+ years. "Racial equality is a Jewish plot against white people."
If you bother to read the Bible, the world has enslaved and humiliated people of color because of a biblical verse where Ham laughed at his naked drunken prude of a father.
Humanity should be better than this. Jesus was better than this. Because the reckoning for bigotry is coming.
