You accuse me of being on a 'moral high horse', but even after you describe with a 'broad brush' some of the discriminations in the north, you still come back to accuse me of being on a moral high horse. Amazing. Sir, it is YOU who are on the moral high horse (along with your compatriot LLAN_DDEUSANT).
For example, LLAN_DDEUSANT totally blames the South above for 'making' northerners conduct the slave trading business because, he says, the Southerners were willing buyers who created this market. He once again attributes no moral responsibility to the north. You people's logic is beyond comprehension by this 'illiterate' southerner.
But, you and I have corresponded before, and we both are fully aware, I'm sure, of the disgusting opinion we have of each other.
