White supremacists: living proof they're dead wrong
The ultimate irony of white supremacists is that I've yet to hear of one who did anything great or even halfway impressive; hence, their lackluster lives manifest the preposterousness of their belief.
In The Psychology of Racism, Roy Masters brilliantly explains the etiology of this racist devaluation of others by unimpressive people as their only way to make themselves feel good. They put others down so they seem greater in comparison, but the only ones they are fooling are themselves.
Consider Dr. Thomas Sowell, Justice Clarence Thomas, Colin Powell, Condoleezza Rice, Herman Cain, Larry Elder, Professor Walter Williams, Lt. Col. (Ret.)/Congressman Allen West, Angela McGlowan, Michelle Bernard, Star Parker, and George Washington Carver who, as I pointed out, was probably a better inventor than Thomas Edison. Or consider President Barack Obama. Even if you disagree with his political views, you must admit that he is an exceptionally clever political genius; anyone who can rise to the top of the highly competitive American political system is by definition a political genius. What do white supremacists think about such people who could run rings around them? Supremacists must be delusional to think they're superior just because their melanocytes pump out less melanin.
Anyone who is tuned into reality knows that skin color is clearly not a good foundation for asserting superiority. Since this is utterly obvious, white supremacists aren't just wrong; to put it colloquially but accurately, they are nuts.
