So-called “identity politics” have been on the rise for some years. Growing scholarship and discussion of systemic disadvantages against demographic groups has led to a rising and justified righteous anger against those forces. But especially in recent years this has resulted in a tendency for every social issue to be framed with a racist or sexist lens. The most outspoken purveyors of this framing are so sure of their analysis that their righteous anger has turned into self-righteous anger. 
Their quest to unite the disadvantaged through aggressive inclusion has actually backfired in division, an idea explored by the Guardian just last week.
My own sense of the perilousness of this approach has been growing slowly, but it crystallized in part while I was recently reading Tracy Kidder’s now-15-year-old book Mountains Beyond Mountains. While debating whether to write a full review of that work in the style of my previous book reviews, several editorials emerged which highlighted for me the most important takeaway: “identity politics” — which militantly reject debate and elevate tribalist and personal “truth” at the expense of individual liberty — at best waste time and at worst threaten the foundational principle of open debate in a free and progressive society.
