The evidence is clear in the choices people make. There are very clear gender differences in what people choose to study, and the jobs they subsequently pursue. You can’t simply blame ‘systemic oppression’ or ‘hostile environments’ for this, as our universities and tech giants all embrace liberalism and feminism to an extreme degree. How can environments that implement ‘safe spaces’, that provide systemic advantages to women, and that have 0 tolerance policies for anything that could be perceived as sexism possibly be perceived as hostile? Yet those environments are the norm now, and women are still far less interested in STEM than men.
