You can twist and distort history all you want but it doesn’t change the fact that we’ve been taught that the Civil War was about slavery. I think your history needs a bit of work, the south demanded that the North vacate their territory and the north refused. The aggression was from the North that refused to allow the South to leave the Union. The North could have reached a peace agreement and allowed the southern states to secede without a war. That wasn’t the goal.
