You could dismiss these concerns as activism, but that's terribly tunnel-visioned.
Only for some values of terribly.
Every African and every women who for some reason
or another has missed out on the opportunity to study STEM is another mind that could potentially have been another Euler or Gauss
but was denied the chance. Unless women are intrinsically less adept at math (which I personally do not believe is the case), we've
been missing out on half the world's great mathematicians.
Well I'm glad you're willing to bet the future of the human race on a personal belief. I on the other hand want to see proof of what you claim.
Could you imagine how different the earth would be today if we had two
Fermats, two Euclids, two Poincares?
Hell, why stop there? I'd aim a bit higher: two hundred Einsteins! Imagine what the world would be like if it wasn't how it is!
How much knowledge have we lost for the lack of women in math and science? This isn't about
"leaving math and science alone" from activism. This is about untapping all the math and science talent that has been hidden away
for hundreds of years.
No, it's activism. It's you putting some naive notion of equality together with a linear extrapolation on the number of geniuses to claim a justification for messing with a system of knowledge that's been evolving for nigh on two thousand years.
Personally, I want my mathematicians to be socially awkward, highly pedantic, focused individuals who would be happy to live three quarters of their adult lives in a darkened room full of books (aka a library), have people to cook for them and tidy their bedrooms. And to be honest, those qualities probably select for white, male, and privileged in our current world, but I don't care.
