You also seem to argue for blank slate dogma (that every group difference is caused by unfair government policy or societal "bias") and that provable facts must be silenced unless accompanied by their detailed etiology (which cannot be scientifically or factually verified, and therefore really just serves social purposes). I would argue that we should teach meditation in schools, every day, and that society should be more empathic and less judgmental. It should also be less afraid of truth, and less politically biased.
I'm arguing that none of the problems you bring up would be a problem with sufficiently advanced AI. They would move us towards the truth, not away from it.
Journalism's current credibility crisis stems solely from its attempts to be "socially useful" rather than truthful. I'm not sure why we should make AI copy us (again ironic since you're against AI taking on human biases).
