And by blaming it all on Lincoln you ignore Wilson, both Roosevelts, LBJ, Nixon, and all the presidents in between. Your beef with Lincoln is he opposed the Southern rebellion. My contention is that by doing so he did what he should have done.
All the ones you mentioned were all terrible. I just see it as starting there. To be very clear I abhor slavery, and I’d die before I let anyone try that to anyone here, but we are also close to it in our current age.
