Fascist political theory builds the state and its institutions hierarchically, based on human difference. It is politically conservative because it tends to justify present stratification, hierarchies, and patterns of domination, such as men over women. People like Jenson, Shockley, and Edward Wilson contend that refusing to follow out and act upon biological conclusions is a political refusal that shows lack of courage to act on the results of modern science. In short, it is anti-scientific and irrational. Politically correct is scientifically incorrect.
Democratic critics respond vehemently that good science leads to no such conclusions.
Stop reading and ask yourself why. The early behaviorist, John B. Watson said that, given any baby, by setting up an appropriate conditioning program he could turn that child into a doctor, lawyer, merchant chief, or common thief. The basic issue is that of nature vs. nurture, or biologism vs. environmentalism. Instinctive vs. learned behavior. Distinguish biological evolution as a fact from evolution as a theory.
