{{Cquote|There are two predominant reasons that can explain why sexism exists in the atheism movement. The first reason is the influence of [[social Darwinism]]. Philip Kitcher, professor of philosophy at Columbia University, wrote in ''The [[New York Times]]'' in 2012 that the first tenet of social Darwinism is the belief that “people have intrinsic abilities and talents (and, correspondingly, intrinsic weaknesses), which will be expressed in their actions and achievements, independently of the social, economic and cultural environments in which they develop.” A concept such as “men are from mars, women are from Venus” is one version of such gender-essentialist, social Darwinist ideas.
