I agree with you, but as a side question on this topic let me ask:
Why is gender bigotry seen as more acceptable then racial or religious bigotry?
If this person had written that black people are genetically too stupid to be good programmers would anyone outside of the KKK be defending him? If he had repeated some 1930s Nazi “science” that “discovered” that Jews were inferior and therefore couldn’t be as good coders as non-Jews would anyone be taking his side?
Be he writes that females are genetically inferior to males in the skills needed in tech and people are defending him? How does that work?
