All races have been slaves. All races have purchased and sold slaves. Whites sell whites today into the s e x slave market. Most Black slaves were sold by Blacks. Chinese slaves were sold by Chinese.
The social debate today isnt about slavery. Its about racism.
Racism in todays society didn't start because of slavery.
N*****, Y**, polock, Yankee, , Nazi... Any derogatory handle spoken, thought, or applied form of racist expression didnt begin with slavery and certainly isnt represented by the American Flag.
Statues of Confederate leaders who fought to maintain slavery are a much different story.
