Yes you do. And you know it because it has been drilled into your head for your entire life.
Demonstrating with modern agriculture maps and historical accounts that it was impossible doesn't even make a dent in what you think you know.
Once again, nobody could have made any of the territories produce wealth from slaves, the entire fight was about controlling congress and changing existing laws which caused money created by the South to flow into the North.
Yes, the Northern people who collected this money spent quite a lot of effort spreading astroturf and propaganda about slavery, but the money numbers speak for themselves.
See this pile of money? Vast bulk of it was produced by slaves!
