It DID NOT stand for that, and it DOES NOT stand for that today either. It has already been explained in this thread what it stands for, which has absolutely NOTHING to do with slavery. 90% of southerners who fought in the civil war (especially in the mountain states) never heard of the Confederacy, never heard of Jefferson Davis, never heard of slavery, and with, TV, radio, computers, many did not even know that black people existed.
You think the people in the photos in Post # 67, support slavery? You need to calm down, and realize you haven't thought this one out.
