Critical Theory was developed by secular German Jews from the Frankfurt School who were shaped by the rise of Nazism.
They wanted a new and comprehensive moral philosophy based on oppressor/oppressed dynamics and group identity.
In other words, shaped by their experiences as a minority group that was oppressed.
But the philosophy they developed is not backfiring and the left is startled to see that the same masses that buy into Critical Theory concepts are turning on the Jews.
Why is this happening?
It turns out that Critical Theory is a flawed Frankenstein's Monster, with the capacity to turn on its creators.
