No, you're just wrong.
Look at where Blacks don't face White Supremacy -- South Africa, Zimbabwe, Somalia, Liberia, Malawi, Nigeria, Burundi and Sudan.
Why -- They're just kicking ass. I think the Central African Republic is getting ready to launch a manned-mission to Alpha Centauri (C) in the next few Months.
In fact, it is known fact that if it hadn't been for Whitey, Mozambique would have developed FTL (FasterThanLight) Travel.
But Whitey fucked that all up. Somehow. We know we did. Somehow. Not sure how, but we did. And just think about Rhodesia, at one time the bread basket of the entire continent. Blacks took it over and created the highest inflation in human history!!!
That's an accomplishment nobody will ever exceed. Blacks can work miracles when Whitey's not arounf to fuck everything up. Zimbabwe is proof-postive.
