The theory of evolution is descriptive, not prescriptive.
I'm not sure why any religious person would fear understanding the world around them.
Nietzsche prostituted Darwin’s idea of “survival of the fittest” and the Nazi’s prostituted Nietzsche’s “supermen” idea to justify their mass murder. Men always become monsters when they make themselves gods because the end point is their own will. It explains why Stalin, Hitler, Mao, et al always suppress religion.
