Someone who identifies as progressive and parrots meaningless and inconsequential identity politics, but is economically very firmly right wing. Shitlibs believe that the mainstream media is infallible, that large
internet corporations shouldn't be subject to any restrictions by the government, that putting issues
like labor rights, the cost of living, and healthcare over
racism and sexism in terms of priorities is dangerous, that Joe Biden is beneficial to the working classes, and that the American democratic party is a beacon of goodness and morality. If you point out that none of those views are progressive, left wing, or just plain true in any way, shitlibs
will tell you that you're a right winger and/or a
Russian agent. Shitlibs are essentially exceptionally committed neolibs.
