If there’s anything about this part of our history that needs to be preserved, it’s what fucking losers the Confederates were. We should be celebrating Confederate L day as a holiday, though it might be overshadowed by Lincoln’s assassination just 5 days later on April 14. I don’t think I ever realized or thought about how close together those two events were, I just assumed it was some longer amount of time after the war concluded.
Also, the Wikipedia page on this time period notes that the inventor of Coca-Cola was a Confederate Colonel (John Stith Pemberton) who became obsessed with pain-killers, which is why he ended up making Coca-Cola (which had cocaine in it originally).
