The really stupid thing is that people still believe it was all about slavery! This is only one proof that it couldn't have been about slavery ( There are many!):
There were more anti-slavery societies in the South than in the north. Why? Because more people here resented slavery because most people here were poor and couldn't afford slaves and they had to compete with the rich people who could afford slaves and bring more things ( produce, livestock, farm products, etc.) to market and do it cheaper! It was the 1800's version of Walmart vs. the mom and pop shop!
* They are now creating fake history by producing supposed documents which talk about the Southern people wanting slavery etc. This " Proves" the war was about slavery, never mind the fact that the slavery institution was on it's way out even before the war started because it is an economically untenable mechanism!
