“Louisiana doesn’t properly teach about slavery, therefore critical race theory is good” is not an argument that logically follows.
I've long considered Abraham Lincoln the greatest leader in U.S. history. But lately, increasingly, I've been forced to reconsider that position. Had the Union been far more punitive towards the Confederacy, I think that at the current moment, we'd all be in a far better place.
I still think Lincoln’s plan would have been better. What happened in actuality was Johnson was too lenient while the Radical Republicans were too punitive (breeding resentment). It was like the worst of both worlds. The more moderate course championed by Lincoln might have been better long-term and allowed for smoother re-integration of the South into the US without either leaving them resentful for generations or letting them just get away with everything. But I guess we’ll never know.
