Isn't it odd that all of the worlds racists are really dumb with low IQ's and no brain?

People like George Washington, Abe Lincoln, Henry Ford, Charles Lindbergh, Winston Churchill, Adolf Hitler, Gandhi, George Patton and Richard Nixon etc all had really low IQ's and were really stupid people. Why do people respect these buffoons? What ever achievements they are credited with it's obvious that they stole them from more enlightened individuals. Anyone who is racist is WRONG! about everything!
