It's interesting, and concerning, to see the exact same thinking in the US today.

The claim was that theoretical, mathematical models of physics, like special relativity, were a product of "Jewish thinking," designed to deliberately confuse the world.

There's a recent video in which Tucker Carlson interviews Jess Elofson and they mutually agree that algebra is nonsense, with Elofson calling it "fake math". They didn't go so far as to relate it to some ethnic source (from the part I watched), but "designed to deliberately confuse the world" is the big selling point. The people they hate are people smarter than them.

On the plus side, this is why these anti-intellectual movements always fail, because in the end they just can't get much useful done, other than attacking and destroying which doesn't require finesse or understanding.

Edit: I have to retract what I wrote about not relating it to an ethnic source. Elofson literally used the term "goy slaves" in that interview.
