I don’t claim to understand, but it’s still a theme.
Maybe it’s an elite vs mass culture anti-semitism? Lots of internalized hatred among ‘bougie’ white and black people towards their respective poor strata; why would a Jewish person interested in reactionary politics spare the normies who, on the whole, abhor it?
Ironically, the same is true of Karl Marx! His father converted to Lutheranism and Karl was baptized as such.
As a young man he wrote a paper on the topical question of the Jews in Prussia[0], regarded in the modern day as antisemitic, though probably tame for the era.
