What does Maryland, whose leaders decided not to secede, have to do with the confederate states that did? Saying that the Civil War was not about slavery because some parts of Maryland had slaves and did not secede is like saying the American Revolution was not about objections to King George because the Canadian Colonies had taxation without representation yet did not declare independence.
Truly a dumb argument. Why do you post such crap?
In this very sentence you allude that the war was about leaving, and not about slavery. Bravo. You proved my point that the war was not about slavery.
Again, if the Northern reason for invading was slavery, they would have started in Maryland. Their reason for invading was not slavery, therefore the war was not about slavery.
