You're the one that suggested America isn't great because of the indians and slavery.
So my question to you is... what other country hasn't enforced slavery? How is that not an honest question? AFRICA had slavery. AFRICANS sold AFRICANS into slavery.
Why did you even bring it up if you weren't prepared to talk about it?
Forget slavery... What about the seperate but equal policies afterward ?
