It's absurd that this is even a debate in our society. Scientific? Everything we know about genetics, hormones, and psychology clearly points to gendered differences and if you objectively look at the data, at the very least you must concede that you cannot conflate inequality of outcomes with inequality of outcome opportunity without gratuitous handwaving.
Progressivism in the US takes as a given that men in the past were backwards and ignorant - but there are literally tens of thousands of years of social wisdom in history that are being thrown away because people can't handle the fact that in this world there are no guarantees of equal ability across groups. Anyone who is offended by such a notion is hopelessly naive - but I suppose you can hardly blame someone after spending a lifetime indoctrinated to pretend that gendered differences magically disappear above the shoulders.
