Rich Lowry of National Review Online ponders the future of the political left’s reliance on identity politics.

For the Democrats, no activity is immune from reflexive accusations of sexism and racism, not even soul-searching.

The initial postelection debate on the left has brought some tentative breaks with the party’s oppressive and self-limiting identity politics. And they have been met, predictably, with a furious counterattack wielding all of the usual rhetorical weapons of identity politics — lest fresh air penetrate the intellectual and political hothouse where transgender bathroom issues loom incredibly large and it is forbidden to say “all lives matter.”

Rep. Tim Ryan, an Ohio Democrat, is mounting a challenge against House Minority Leader Nancy Pelosi, and argues that Democrats are hurt by a paint-by-numbers view of politics. “We try to slice the electorate up,” Ryan said on Meet the Press over the weekend. “And we try to say, ‘You’re black, you’re brown, you’re gay, you’re straight, you’re a woman, you’re a man.’”

Ryan might have pointed to a critique of his own leadership bid by a writer at the website ThinkProgress, who opined that his run against Pelosi “is how sexism works.” How so? Ryan is a male; Pelosi is a woman. Q.E.D.

Outside of its political effects, this style of argument is childish and intellectually deadening, yet is too ingrained and widespread on the left to be extricated easily.
