Perhaps this fictional scenario might be illuminating: Imagine if Africans colonized (sorry Tony) Europe and set up a slave trade, shipping white Europeans to Africa and subjecting them to some of the most brutal, immoral, violent and inhumane treatment imaginable. They separate families, punish them for speaking their native languages and practicing their traditions. The slavers gang rape the men in front of their families. They gang rape the women in front of their families. They gang rape the young children in front of their families. They whip, chain, hang, torture, and burn alive the white slaves. They bury them alive.
Forcing them to work 18 hours a day is a respite from the aforementioned brutality.
The white slaves eventually win their freedom, but are immediately relegated to second class citizenship. They are terrorized (sorry Tony) by cloaked riders in the night. They are lynched without trial. They are denied the right to vote and denied education. Hospitals refuse them admission. They are humiliated in minstrel shows, where the Africans paint their faces white and wear blond wigs, and use cheap stereotypes to garner laughs and perpetuate the idea of the subhuman white, which they use to justify repressive laws and codes.
Imagine 150 years later, when whites are still fighting for their rights, and Europe is still struggling, blacks are still occasionally seen painting their faces to mock whites.
How would it make you feel?
