After the slave trade stopped, why didn't the American government send all blacks back to Africa?

There are no stupid questions, only stupid answers. ...

When you say "the slave trade stopped", do you mean that 1808 was banned by law? At that time, the mainstream of American States was against slavery. There are only two stubborn states in the south, South Carolina and Georgia, which rely heavily on slaves as their labor force economically, and they insist on using slaves without a strong Christian humanitarian foundation in the north. The racial problem in America is too complicated. This is definitely not just a question of racial discrimination. From the perspective of English translation, racial discrimination is better. "All men are born equal, and people have inalienable rights to life, liberty and the pursuit of happiness" is the foundation of their founding. Therefore, before the Civil War, most Americans thought that it was natural to liberate slaves, but because of the huge difference between barbarism and civilization, they still wanted to let blacks live alone in one place and stay out of it. Individuals in the south are more extreme, but slaves are their property. Like a house, except for a few sadists, it is generally good for slaves. After the civil war, white people in the south were somewhat dissatisfied with black people. After all, the south is basically burnt. However, in the north, when the two races freely merge, serious conflicts will inevitably occur due to cultural differences. I suggest going to see Amistad. White people want to send it away, and so do black people. I'm interested in leaving a q before we discuss it.
