Because tech culture has skewed so insanely towards the authoritarian left that any challenge to the orthodoxy your post suggests is immediately weaponized. There is simply no way to honestly discuss the points you bring up without putting one's reputation and eventually career in danger. The Damore memo is a perfect example of this. The only safe thing to do in our culture right now is virtue signal and nod along with the rest of the mob. Perhaps one day the madness will pass and we will be able to again ask hard questions in public and try, together, to get to the bottom of things. Until then, lets just not talk about these things, so that a great many of us are not forced to wallow in hypocrisy for the majority of our waking hours.
