There are so many people who still deny the cruelty of slavery. So much of their beliefs are based in horrible lies.
The thing is, I don't believe that they believed what they were peddling. They were only trying to morally justify their oppressive tactics.
Still, many white Americans embrace the Confederate flag and defend the Confederacy. You are also right about the North. They did not want to face the discrimination in their own backyards. Thanks for writing this article. It's well put.
