I'm a college student, and my major involves a lot of STEM classes. The intro classes are open to everyone, but the higher up classes require a pre-requisite of the lower level classes. I notice many women in my psychology and sociology classes, which I'm required to take as general education courses. But I see very few women in my STEM classes. When feminists complain about women being underrepresented in STEM fields, it's simply because women choose to go into other areas. The few women in my STEM classes are treated just like everyone else. Some of these classes are even online, so the tests and quizzes are literally graded by a computer. STEM classes are open to everyone, and the only reason women are underrepresented is because they choose to go into other fields.
