Taking your statement as a legitimate point, I think the issue isn't that having a vagina means you should be treated differently (side point: not all women have vaginas; don't down vote me). In tech we like to think that everything is a meritocracy but we see countless examples where company culture has made it difficult to exist as a woman. Think of the numerous complaints from women working at Uber circa 2016-2017. Or the thousands of high profile #MeToo allegations. Men being in the dominant and default in tech means it's easier to get away with crap like that. Ensuring that women are adequately represented means that type of stuff is harder to get away with. If more equal representation makes workplaces less toxic, then it's worth it for that alone.
