Scientific racism is real science that we see everyday but is stomped and kept hidden. Just ask James Watson Nobel prize winner for his finding on DNA and who had it stripped away from him, ostracized for pointing out such science as true.
What is this scientific knowledge from the past you are not suppose to know and the same science Adolf Hitler lived by?The scientific factual belief that the human species is divided into biologically distinct taxa races of species, and that evidence exists to support and justify racial discrimination, racial inferiority, or racial superiority.
It's science based on what is woven into us that makes us. The division of humankind into biologically separate groups, along with the assignment of particular physical and mental characteristics to these groups through constructing and applying corresponding explanatory models.
In new age science of the 21st century based off this banned Science of the past and in recent years specially. It is theorized that black people aren't really human at all but a sub species of tri-on humanoid apes who are animals that mealy imitate human mannerisms.
