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.
I actually saw that comment first hand and it was in the middle of a thread I was in and I got so fuckin mad. As someone who has been food insecure myself for most of my life and currently cannot afford a kitchen and will be hungry till I get to work and heat up my little bowl of 3 bean chili honestly seriously fuck that person that said that and I am glad they are gone.
