Ok, so we've moved the goalpost from *women can't perform as well as men at math* at least to *women can, but only men have that wider range that leads to true exceptional genius*.. that's a start...
Which is an interesting proposition with a very short historical sample size to draw from, given that up until the mid 20th century it was difficult for women to enter the sciences. And even in time periods when women were discouraged from doing so we still find women who are exceptional such as Emmy Noether. Computer science is also interesting given that women were quite active in the early days, and we've Grace Hopper responsible for developing the first compiler.
I think it ironic to mention 'not admitting sex-based difference' when at best sex-based difference in studies gives us -overlapping distributions- not -separate tidy boxes- and really only for certain kinds of thinking that are difficult to disentangle from nurture/environment. Neuroscientists have only begun to map the human brain, and both men and women are affected by hormones with conflicting studies saying what hormone does what. There is little clear evidence as to what sex-based biological capabilities/differences actually are and they don't affect math skills in tests accounting for cultural bias. Second, perhaps that one in a few thousand men had the qualities of 'future leaders' speaks volumes about traditional thinking, presupposing that only certain men with certain fetishized qualities are chosen as leaders based on old paradigms. There is certainly no historical basis for such a claim given that even despite the limits placed on women throughout history you still find women breaking the rules taking leadership positions, sneaking into battles, writing novels under pseudonyms, being renowned as philosophers and mathematicians, being fully capable of insanity, capable of a lot of things, really, rather. Oh, and being ignored from history due to plenty of men who think women belong in the home (see balzac).
It all comes down once again to turning descriptive statements into prescriptive roles. For example, confusing descriptions of cultural habits with biological differences, and then making prescriptive statements about gender based on that combo.
We are capable of dealing with suicide, homeless men, autism (whatever autism turns out to be) AND sexism. We are also capable of dealing with viral epidemics, PTSD in soldiers, so forth, AND sexism. Humans are capable of separating different problems into different boxes and tackling them. There's no need to conflate separate problems.
