Probably the opposite, but I think he is honestly trying to suggest that the South could have been negotiated out of chattel slavery. He's a moron, let's not forget that.
This orange asshole is completely surrounded by White Nationalists, Neo Nazis, KKK Members, Confederate Apologists, etc. etc. They all sit around spewing this shite to each other and then he plays their greatest hits on stage to the Qult45 crowds.
For people who fly the Confederate battle flag it's really lost all original meaning and they just fly it to be edgy and whisper their racist opinions.
I attended a historical reenactment of the 17th century near the northern Iowa border that used to be fun pre-trump and saw so many flags that should not be (trump flags, combo trump/American flags, combo American/Confederate flags, pure Confederate flags, you name it) it really felt like the trumpists pushed out some of the history nerds who were there to nerd out over pre-colonial history
Before the war, Lincoln wasn't an abolitionist. He wanted to stop new states from having slavery, and keep no slavery where it was. He was fine with letting the south keep their slaves for the sake of the Union.
The problem was the South did not want to limit their potential to grow slavery to new states, and decided to go to war over it.
Still doubt negotiation could have worked. Lincoln really did not want to go to war in the first place.
I judge people more by their deeds than their desires, especially their desires before the fact. Lincoln ended up doing the right thing. He also ended up successfully seeing the country through one of the most difficult times, if not the most difficult time, in its history. He is, to me, rightfully regarded as one of our greatest presidents regardless of his thoughts on slavery before the war.
