All of that is true. In fact, the 3/5 compromise built into the Constitution may have made the Civil War inevitable. And while the problem of race relations has been an open sore in our country, it still remains that essential core of our country, and all of western civilization, was built by white people. By that, I mean:
Railroads, Steamships, Automobiles, Aircraft
Telegraph, Telephone, Satellites, Cellular phones
Computers, Television, Video Recordings, digital data storage
Coal, Oil, Natural gas and nuclear power
Breech-loading firearms, repeating firearms, machine guns, armored fighting vehicles, quick-firing artillery, ballistic missiles, thermonuclear weapons....
Falsifying history does nobody any favors, to be sure.
Still the problem isn’t one of skin, but of sin. Modern colored immigrants from Africa laugh at the idea of racist woes in America.
