You have mis-represented just about every point the Google engineer tried to make. He did not say “ some large fraction of his colleagues are at root not good enough to do their jobs, and that they’re only being kept in their jobs because of some political ideas,” he said that “We need to stop assuming that gender gaps imply sexism”, as every serious study has shown that the so-called gender gaps are created by the different choices that men and women make, especially about work/life balance.
He says in fact that women are underrepresented in some occupations because “These positions often require long, stressful hours that may not be worth it if you want a balanced and fulfilling life.” He clearly admires women for making better decisions than men do. How is that sexist?
Then you start just making stuff up, and virtue signalling that you reject his politically incorrect ideas: “What you just did was incredibly stupid and harmful.” Bull. He tried to raise the problem of the Google culture publicly shaming anyone who doesn’t agree with the whole pantheon of Left Wing politically correct dogma. Virtually everything you said after that quote was a lie. You completely ignore his suggestions for making the workplace more attractive to women, for instance, and I find your faux outrage unconvincing. If you ever held a high managerial position in Google, God help the people who worked for you. Seldom have I heard such a hatchet-job on a well-meaning employee.
I think you would be surprised how many women would agree with much of what he said. There is a reason men make up 93% of the deaths by workplace accident, and why women are also underrepresented in “coal mining, garbage collection, and firefighting.” If you want more women in tech jobs, make them more family-friendly, with flexible working arrangements, less like “coal mining, garbage collection, and firefighting” than it is now.
I would not work for a boss who spends all his time shooting the messenger, and none addressing the message itself.
