I fail to understand the outrage but attribute that to the fact that few bothered to readRather than assuming those who disagree with you are shallow and hysterical (a contentious word choice, given the subject), perhaps consider why others might be outraged, you could try some empathy (though I know the article warns us against empathy).
The doc presents a point-of-view, grounded in reality. Furthermore it's not "anti-diversity", but rather anti-discrimination
I think it is explicitly anti-diversity in that it sees nothing wrong with the current order of things, if that order can be justified by failings in the weaker vessels that surround the author like empathy and neuroticism (as the author clearly thinks it can).
It does seem a remarkable coincidence that the natural order of things so neatly reflects the author's place at the top of the pyramid though, almost as if the rules had been written by people just like the author.
Since when is dialectics grounds for ostracism?
I doubt the author has faced ostracism, he certainly seems confident enough in expressing his disdain for a large number of the people he works with, without apparent fear of consequences. Since dialectics is usually taken as a search for truth, here are some things that the author believes which are not true:
Women are not more neurotic than men
Women are not less scientific than men
Women are not more interested in feelings and aesthetics than ideas (a curious dichotomy)
Women do not innately prefer jobs in social or artistic areas over say engineering
