“The North had the moral high ground.”
No.
I say that based on what the North did to black people before Lincoln’s war. And based on what the North did to black people during Lincoln’s war. And based on what the North did to black people after Lincoln’s war.
Does your incessant repetition of calling it “Lincoln’s War” make you feel like you personally have the higher moral ground over people who don’t use that provocative terminology?
The North had the moral high ground. All day, every day and twice on Sunday.
But there was no time before, during or after Jefferson Davis' war (who provoked, started, declared and waged war against the United States in Union states & territories) no time when African Americans were not treated vastly better in Northern States than in the Confederacy.
