The Civil War was about many things to many people. In Alabama and Mississippi, for example, the secession documents were about slavery. In Virginia, on the other hand, they were over the Federal government ordering Virginia militia to invade seceded states. In the North it was over not wanting to lose power. Texas, well, they just heard there was a good fight and did not want to be left out.
I think I'm coming down in the middle about your post.
I guess I neither agree, nor disagree.
