It took countless man hours for Bat **** Crazy Afro-Centric Multi Culturalists to sift through MILLIONS OF US PATENTS so that they could find a few dozen examples of things that were "Negro Inventions"

The AGENDA DRIVEN LIARS are so desperate.....
Google "Doctor Charles Drew" and also "Negro Invention Hoaxes" for classic examples of what I'm talking about.
