bien-pensant political idealism that saps the energies of any serious movement intent on radical reconstruction.

 There are by some powerful critiques of  current forms of bien-pensant political idealism such as multiculturalism and the rhetoric of human rights – admirable liberal ideals calculated to sap the energies of any serious movement intent on radical reconstruction.

All these ideals (in the US AOC Sanders etc)  presuppose the possibility of some ultimate collective harmony and reconciliation as the operative goal or end of political action. presupposing  a violent rupture with the current social system

Or is such thinking a temporal hiccup of  utopian thinking?
