You can have as much prejudice as you like against white people, argue for ending the concept of family, the idea that the west must cede hegemony on a moral basis, reparations, ending capitalism altogether, implementing any brutally authoritarian form of government you may picture (as long as it doesn't seem right wing), ending borders, dissolving countries, call for the death of the bourgeoisie, and I won't even mention anything related to gender or data centers as I don't want to find out if these comments have a limit on text.
Is there a line? I honestly don't know if there's a line. A renowned Harvard academic could argue tomorrow that all of humanity should commit coordinated suicide and I'd barely be surprised. I wouldn't even bet money that it hasn't happened already.
I'm a liberal myself, really, but it feels the general political current of liberalism has gone through some real excesses and it's bloated and dysfunctional right now.
