Right, but that uses some sleight of hand to make the claim that you can/should adjust for bias everywhere instead of at the source, which isn't something everyone finds fair.
If you are in favor of a revolution, all the power to you... But if not, then I’m sorry to say that our best option is the slow, painful and gradual correcting for our systemic biases for the next generations.
Trying to 'unbias' (meaning a calibrated, countervailing bias actually) at the other end of the funnel, where incidentally 80%+ are already super liberal, doesn't really get the same mileage.
If people are primarily upset about general societal things rather than clear cut workplace discrimination, I would submit they should focus their activism at those societal things.
