I don't remember this being in Mrs. Church's 7th grade history class. Hmmmm maybe it was because I read this book

It's a good read and you would probably do well to pick it up. Then you can understand that your conclusion that Abe came used slavery as an excuse to gain favor with the Brits and the French is incorrect.
You gain a solid understanding of what HE said. Not the interpretations of historians.
You can borrow my copy if you like. Maybe we can trade, can I have your copy of Mein Kampf?
