Prime Minister Margaret Thatcher famously observed that socialism works until you run out of other people’s money. Identity politics also works until you run out of other people.

And then #MeToo becomes #NotMeToo.

Other people’s money can be borrowed against. That’s why we have the national debt that we do. But identity politics has multiplied too abruptly and explosively to postpone the reckoning much longer. What were once simple categories of three races and two genders has mutated into an infinite alphabet of sexual identities, a Big Bang of ethnicities, national, cultural, racial and religious, each with its own microaggressions, that easily tops two hundred and shows no signs of slowing down its expansion.

Intersectionality, the Das Kapital of identity politics economics, tries to manage the complex network of interactions even as it purges Jews and white people. And now it’s even starting to purge men.

The left is running out of other people.

#MeToo, #BlackLivesMatter, the campus purges of ‘whiteness’ and ‘toxic masculinity’, the civil wars within the LGBT alphabet soup all point to the ‘other people’ crisis of the left. The latest social justice wave has made men, white people and even white gay men into hate objects. The resentment coalition of identity politics is fracturing into a tribal war of identity microgroups against everyone else.
