The liberals who control our media are trying to promote the lie that blacks played an important role in the development of Western civilization. They didn't. Blacks played almost no role at all, unless it was a negative, destructive role. But we're all supposed to believe that they are "just like us" or more often lately that they are "better than us." It's a lie. Blacks in America are, in general, of subnormal intelligence and are incapable of contributing anything of value to science or to society at large. There are a handful of black geniuses, but only a handful, and they are not at the level of most white geniuses. That's a fact, which no amount of liberal disinformation can change.
