Then how come through the entire history of mankind across the entire globe blacks have always been the bottom of the barrel?
In Africa when everyone else was building ships, sailing across the oceans, setting up trade routes and so on blacks were sitting in huts with dirty balls enslaving their own people to sell.
There has never been a first world black country, ever. There has barely been a second world one.
Out of all of mankinds progress made in aerospace, engineering, science, medicine, physics, space travel, architecture, electrical and so on blacks have contributed very little. Even down to efforts like the aglet for shoelaces.
We're talking across the world throughout history they have consistently been the poorest performers, even in their own countries among their own people. You can't blame American history on that.
Even in today's society where blacks can be racist but whites can't, they get to get jobs based on their skin color when whites can't, they get admitted into colleges based on their skin color, they get special treatment and consideration for being black, all media is full of them, companies demand diversity quotas, even BLM can loot and riot for years under the banner of blacks and virtually nothing happens to them. But yet they still are in last place in America?
No, I am completely correct. You just won't look at observable realistic facts and admit the truth.
Not all blacks are inferior, Thomas sowell proves that, but the majority of them are. Nothing wrong with last place, someone has to be. But all you have to do is look at the world and you'll see not everyone is equal despite every opportunity and centuries of time to be equal.
