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.
The most important thing is that liberals believe that just making good statements and public signals (like "I am voting for Democrats and Democrats are good because I say so and when I vote for them I am a good person by definition") makes you good and is the most important action someone can do. Sure, I supported the Iraq war and exploit my employees and steal wages from them, but I have this great lawn sign that makes me a good person.
Drunk out at a brewery the other night me and a friend were ragging on this lib about how shit Obama was and when he couldn’t find a way out he just started stating loudly and repeatedly that Obama was hated by americans “because he’s a SMART BLACK MAN.” Like dude sure but we’re talking about fiscal policy here wtf are you doing? Liberal ideology is a radical experiment in self-perpetuating sloganeering
Same energy as libs saying "If you don't like Hillary/Warren/Sinema, it's because you're a misogynist"
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. Funnily enough he essentially said that Warren would’ve ushered us into a new golden age if she had won in 2020, to which my response was even Joe fucking Biden couldn’t pass legislation through this senate wtf was she going to do?!
