9/11 is never forget because it was a terrorist attack on an otherwise docile nation. I get that the slaves technically didn’t do anything either but keep in mind, the wealthy kings of the African civilisations SOLD THE POORER BLACKS to the settlers who put them to work. On top of that, it’s a much more recent event, and one that has plagued mankind since the dawn of time. Nobody cares about the white Irish slaves? Or the Egyptians who enslaved each other? Then why should we still care about you? I rest my case.
