Some excerpts below:
"However, when an ideology contends that some people are less human than others ... we must reject that ideology as evil."
The "science" that some people are inferior, so less human, is called eugenics. The Nazis were the pinnacle of this science but major American universities, including MIT, have a history with eugenics.
Up until surprisingly recently there was a scientific consensus that blacks were mentally inferior, i.e., less intelligent, less human. (I use the term "black" instead of African-American because I am not just talking about Americans.)
Mooney makes it clear in the book, using some "scientific research" he and his mother did, that the Republican brain is inherently inferior. Thus Republicans are less human. The book has been denounced by many as just eugenics.
