In this thread, no I haven't explicitly seen that argument being made. It is, however, an outcome of those arguments.
Can I just stop you there. How is it simply 'an outcome of those arguments' or indeed 'ends up supporting the continued disadvantages for women'?
Surely you mean, 'risks being one or both of those things'? Which I would agree with.
Sorry, but I'm still not in favour of an embargo on such things on that basis, especially when there is as yet no obvious sign here at least of the implications you are concerned about, and quite possibly I am not in favour of the relevant facts being avoided beyond this discussion either. It seems anti-scientific and anti-rational skepticism to me. I acknowledge the risks you validly mention, obviously.
For the overwhelming majority of history, women have been treated as subordinate to men. In many parts of the world, they still are, and explicitly so. As women began seeking equal rights, they were met with substantial justification for why they shouldn't have equal rights, or why differential rights were appropriate. Even once we got the right to vote and were hypothetically treated equally, gender bias remains. There are many people alive in the US right now, today, who believe that women are simply more suited for caregiving jobs than for leadership roles. The believe, and argue, that women have evolved a nurturing psychology, and they're naturally more empathetic and easy going. They believe, and argue, that men have evolved to be more aggressive, dominant, and decisive. This, they argue, is a big reason why there are more women nurses than there are women doctors. This, they argue, is why there are more men in STEM fields, and in executive positions, and in politics. Because it's the natural outcome of men and women being biologically different.
Because their brains are different.
Because this viewpoint, this belief, and this argument exists already, and because this viewpoint presents an actual barrier for women today... that is why I say that the argument from "different brains" leads to the continuance of a deeply rooted social disparity. It need not be intentional, but that is part of the outcome.
In the same way, if someone were well-intentioned and genuinely just fascinated by brains, and proceeded to come out with evidence and arguments showing that black people and white people have different brains, that would be used to support the continuance of racial bias and disparity. The difference that I have observed, is that someone brings up scientific support for their argument that black people and white people have different brains, their agenda is immediately questioned and there is consideration given to the impact of that support, as well as skepticism about whether or not that difference is meaningful in any legitimate fashion.
I haven't observed that same questioning and skepticism when the argument is that men's brains and women's brains are different.
