Denouncing chauvinism in particular is like a liberal moral event horizon, a cardinal sin against their self-interested belief in the righteousness of the imperial hegemon that keeps the treats flowing at gunpoint.
And they’re not wrong that these people get hate for racist/misogynistic reasons, but they also get a lot of well deserved hate based on their policy decisions.
