The Dumbasses need to take some remedial history courses away from Marxist. Racism as it is known today existed in the north and south all the way up to POTUS before, during, and after the Civil War. The Civil War was a war over economics and states rights to self rule. Slavery was legal in many states in the north up to the day of the first shots fired. Many of the Generals on both sides of the war were former West Point Classmates and settled their differences after the war. That included Grant and Lee. Also ignored in modern history is the fact Lincoln was a segregationist. His intentions or his idea was to return slaves to nation of origin.
Not quite the case, You stated “Slavery was legal in many states up North to the day of the first shot fired.” Maryland ended slavery in 1864, Missouri in 1865. The states of Kentucky and Delaware did not end slavery until the adoption of the 13th Amendment to the Constitution in Dec.1865.
