If you count asians as white...
Also gonna want a cite on that. afaik sv hiring is about equal with labor market.
I think there's several claims here:
1) "no/very few women can be good at stem/math/language/programming." Nobody but the most comically self-parodying misogynists says that.
2) "fewer women are good at stem/math/language/programming than men." This is the "SV conservative/classic liberal" position. If equal opportunity is provided, any remaining differences in hiring are plausibly down to availability which is down to average capability.
3) "women and men are just as good at stem/math/language/programming." This is the progressive/feminist position.
The people who hold 3 want the rest of the world to think that the people who hold 2 actually hold 1. Many 2 would be willing to tentatively jump on board with 3, but 3 somehow keep antagonizing them. As such, similarly to the Trump election, it's politically a question of which side disgusts you less.
A random example: taller people and people with broader shoulders make more sales.
We are intelligent minds grafted clumsily onto apes.
Just because somebody's opponents are biased doesn't mean they aren't.
Note that I am not saying that #3 is not the case! I'm saying that I personally have not been given reliable reason to believe #3 over #2, or reason to believe that the people who have tried to get me to believe #3 are competent and respect their own fallibility to the point where I could tentatively trust them.
Ironically, the more aggressively people try to get me to agree with #3, the more skeptical I tend to become of it. To me this is analogous to the AI risk debate, where I at least partially worry about it because the arguments against from otherwise intelligent people have been so consistently lackluster.
edit: To iterate on that earlier "which side disgusts you less" comment:
As with the Trump election, people on either side tend to assume that people on the other side agree with their candidate.
This is not necessarily the case. Often when forced to choose between two alternatives, the question is down to which outcome seems to you more desperate. People who vote Trump consider immigration a desperate struggle. People who vote $not_trump probably consider sexism/racism a desperate struggle. Both sides are willing to sacrifice some values so that they can try and preserve others.
I believe the debate between #2 and #3 is mainly down to whether you consider sexism or knowledge the more desperate struggle. Personally I tend to come down on the knowledge side, possibly because I am not personally affected by sexism. This does not mean I will condone sexism, it means that I will trade it off, if I am utterly forced to, against a value that I consider more vital. That does not mean I wouldn't like to reduce sexism if I could; it does mean that when people are censured due to citing scientific studies, I feel that something I consider more urgent than gender equality is at stake.
In any forced tradeoff, there is only one value that can win. I think sexism and racism are serious issues, but I don't think they are the most serious issues. If that makes me a misogynist in people's eyes, then so be it.
Of course, in any remotely sane civil society we would try to negotiate solutions that satisfy the values of everybody involved. This is a large part of why the aggressive, condescending rhetoric of certain parts of #3 is so frightening to me. I see no reason why the fight against sexism and racism has to be at odds with truth; it's an unforced overaggression that's alienating people like me for no reason.
In summary: my issues are with the #3 methodology, not the #3 position.
I also don't totally reject the notion that biology can explain differences in outcome. I just think that explanation should be a last resort after the far more likely causes of bias, random path dependency, and perverse incentives and feedback loops are ruled out. Blaming biology first is like immediately jumping to "compiler bug" when your program crashes. People who jump first to biology are probably racist or sexist.
As for immigration vs social justice: neither are IMHO existential struggles. Existial struggles are things like sustaining a modern economy post population growth and transitioning beyond fossil fuels before we either crash and burn in a Malthusian catastrophe or destroy our atmosphere and oceans. If we don't fix those things social justice and immigration issues won't matter much to the survivors of the nuclear war that ensues as global civilization collapses.
As for Trump: he is categorically unfit to be president, but Clinton was also an awful choice. That election was terrible and the lineup as a whole symptomatic of the decline of our political class.
I guess I tend to come down more on the nature side of nature vs. culture, but I definitely think that the possibilities you listed are entirely plausible and I'm definitely open to being convinced with well-designed, at-least-not-obviously-partisan studies.
(Amusingly, depending on what language you use, blaming "compiler bug" first when your program crashes can actually be surprisingly credible. Languages like D, for instance, which combine a strong type system with a homebrew backend overburdened with features, make it a lot more plausible than you'd think.)
I entirely agree that neither of those are existential struggles, but we still have to rank them. Personally, I'd rather lose feminist progress than liberal progress, because a liberal, open-minded society will make it a lot easier for feminism to regain ground. What good if we win equality-of-outcome, if it loses us the soul of equal rights? I believe that we ought to think that #3 if #3 is true, and that we ought to think that #2 if #2 is true. To do this, we have to be able to discern truth without bias.
Inasmuch as #3 is true, free thought and civil discourse is its ally in whole.
