> it's starting to get to me how so many people in an innovative sphere seem to have such a hard time with this
The prevailing (cultural) attitude is clearly against plain facts. The question should be why the prevailing attitude is against facts and real solutions but embraces lies and bad solutions. That is what is getting to intelligent people no matter their sphere.
> If the main argument is that women do not [by nature of our scientific understanding] have minds tuned to engineering prowess to the extent that men do for whatever cause
It's not an argument that women's brains are structural and chemically different than a male's brain. Also, there are time tested (1000s of years of history) of observations as to what these differences (generally) manifest in. This is also not an argument.

Socially, you can do whatever you want. However, each such action caries consequences. A company that silences inconvenient truths and doesn't promote those capable of root cause analysis but instead promotes group think centered on flawed thinking and those that skirt around root causes will face the consequences of such a decision. As far as I'm concerned, it's a self-correcting problem. There are plenty of giant corporations in history that are no longer known for similar such missteps.
The rest of your post is filled with hand waiving and appeal to extremes. One group is presenting facts backed by sound logic and science you're resorting to demonization, appeal to extremes, and asserting intelligent people are incapable of philosophical/humanistic conjectures whereas observation proves the exact opposite. What's isn't the scope of a non-intelligent uninformed person is any higher minded thinking or analysis yet they feel the need to constantly interject their half witted opinion into matters and strong arm intelligent people's more accurate and thought out commentary. In the age of intelligence, it will be the half witted opinions that get disposed of and the opinions of entities in support of it and for good reason so that we can truly explore our humanity and our reach without being stunted by those who seek to hold back the truth or progress that can be made embracing it.
