There are all kinds of smart black people

You've been brainwashed by racist dogma into believing that all black people are unintelligent.  Why, turn on the TV, watch any show or movie and you'll clearly see that black people are intelligent professors, teachers, philosophers, news anchors, sports commentators, political analysts, literary authors, human rights advocates, actors, computer scientists, engineers, doctors, chemists, physicists, historians, anthropologists... the list goes on and on.   

George Washington Carver was an inventor and agricultural pioneer, who advocated crop rotation, sustainable agriculture and agricultural education.  He created over one hundred peanut based products including cosmetics, dyes, paints, plastics, gasoline and nitroglycerin.  He patented several hundred applications of peanuts, sweet potatoes, cowpeas, soybeans and pecans, including adhesives, axle grease, bleach, buttermilk, chili sauce, fuel briquettes, ink, instant coffee, linoleum, mayonnaise, meat tenderizer, metal polish, paper, plastic, pavement, shaving cream, shoe polish, synthetic rubber, talcum powder and wood stain.  

Carver's original uses for peanuts include radical substitutes for existing products such as gasoline and nitroglycerin. These products remain mysterious because Carver never published his formulas, except for his peanut cosmetic patent.  From peanuts he patented 30 cloth dyes, 19 leather dyes, 18 insulating boards, 17 wood stains, 11 wall boards and 11 peanut flours, and from sweet potatoes he patented 73 dyes, 17 wood fillers, 14 candies, 5 library pastes, 5 breakfast foods, 4 starches, 4 flours and 3 molasses.

Carver is credited with having introduced the first peanut based writing system, meant to teach deaf children how to read and write.  He developed the first electric transistor using peanuts.  His studies in harmonics lead to the first telegraph system using wire, string and two peanut shells.  His most intriguing invention was a combustion engine that could run entirely on peanut oil, and a series of high grade military explosives using peanut butter as an accelerant.
