Gender studies majors do. See, they make their career out of pushing to get more women into careers that nobody is keeping women out of
Maybe not keeping them out of, but many women and girls are discouraged from entering STEM fields. Both my girlfriend and our daughter were strongly discouraged from STEM fields by teachers, advisors and others. Those people claimed that such careers were "not appropriate for girls." They both said "BS, I'm going to be an engineer." My girlfriend is an engineer and our daughter will soon get an engineering degree. Very few of their classmates who were also interested in STEM (and got A's in highschool science classes) actually went on to pursue STEM degrees.
