Yes I agree with that - I think the argument against their perceived weakness in institutions is that academia/media/tech are generally claimed to be left-dominated by the right. But even if it is, that is not the same as POC and minorities having material power, even in those places. But the historical lack of power is a powerful argument to pursue and use in counter as here - but they have to be prepared for the "well, all those institutions are run by liberals now" response. I don't see anything but weakness in the left's denial of the obvious witch-hunts - they should not protest so much perhaps but examine honestly in good faith the complaint, and bear in mind that while this is currently (mostly but not entirely) a disease of the left, conservatives need also to remember their own equivalent purges in the McCarthy years. This is a human flaw, and acknowledging it while maintaining the right to defend against institutional legacy power structures and discrimination or bias seems a more healthy and constructive way forward.
