There's a difference between calling out a book like "White Fragility" for being useless HR pablum, and whining about "idpol." The problem with White Fragility is that it frames racism in modern America as the unfortunate aggregate of personal failings, instead of the deliberate product of systemic oppression. White Fragility offers the racial equivalent of suggesting we can stop global warming if we all buy a Prius. It puts the blame on the (not fully undeserving, but largely powerless) masses instead of the institutions of power which are responsible for the perpetuation and self-replication of racial inequality. That isn't reductionism. That is synthesis.
