And white men bleed and died during the civil war to change things
We’d be happy to find sending all dissatisfied folks back to Africa
Slavery existed all over the world until the white man put a stop to it.
America, alone in history, fought its bloodiest war to free the black man.
Any debt the USA was paid in the blood of Union soldiers. The Democrat slavers in the south were decimated and paid for their sins. Cities burned.
Slavery kept going basically everywhere else but the Western world. Africa still has a slave trade. The transatlantic slave trade kept going to Brazil long after the USA freed slaves.
