If men are dominant in certain fields, it’s a sign of systematic discrimination against women. If women are dominant in certain fields, then that’s just because men suck at xyz and this is just the natural outcome.
I’m open to having my mind changed, but I think that might actually be true. In cases where men are dominant, we can point to specific discriminatory situations. We can see how hiring committees consist primarily or exclusively of men. We can see how popular depictions of people in [field] are all male. We can note that neurodivergent boys are far more likely to get diagnoses and support than neurodivergent girls. With the exception of certain fields like education and nursing, I can’t think of any systemic factors that discriminate against men.
