Every liberal does it too, from center right radlibs to far-right “conservatives”: the most extreme right fringe liberals hate the mainstream liberals for not being bigoted enough, the mainstream libs hate the radlibs for not being cruel enough, and the radlibs hate the left for not being chauvinist enough.
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.
As the official pod puts it, liberals live in a world full of victims but no victimizers
I wouldn’t put it like that, it’s more that they don’t see doing nothing as political, and consider being aware of the problem or even minor donations as a sufficiently positive action.
