How do we really know race and gender are discriminating factors? Do we look at anything else or are we just making zero effort to do more than just confirm our biases? We might as well take into account their financial background too, for example whether their parents grew up poor. It's about as relevant as someone's race, gender, and sexual orientation when it comes to hiring decisions. Unless it's actually all about scoring useless PR points, or, more sinisterly, cowing to the demands of progressive extremists that threaten violence and negative media exposure. If that's what it's about then we can safely assume race, gender, and sexual orientation are irrelevant when it comes to hiring practices, and instead we can just hire random people that seem remotely qualified (which is what we have already been doing before this madness began).
