Lets get the facts straight and stop pretending...The lawn mower was not invented by a black person and neither was a cellular phone. Martin Cooper invented the cell phone and Edwin Budding invented the lawn mower. Google it! (Google was invented by Larry Page and Sergey Brin by the way)

The quote above is really heart breaking. It shows that black people know very little about the achievements of fellow black men/women. First of all google the name "Mark Dean". He arguably invented the PC, yes personal computer. He holds 3 out of the 9 patents of the PC. Oh I forgot, he is also black. The following are other black inventors that I think we need to know. I agree with afam4eva that a lot has been done to keep the system the way it is. And that's why you hardly hear people celebrating black inventors

Now think of the western world without elevators, lawn mowers, refrigerators, helicopters, gas heaters e.t.c. You will see that black people gave the west their civilization. I do not think intelligence has anything to do with skin color, and if you think it has, then the list above tends towards the superiority of black people.
And I forgot, Mark Dean designed the first cpu that ran above 1 GHz. I think he is currently a vice president at IBM.
