So? From the Haskalah onward, “liberal” judaism has often been ever more influenced by European (and white) racism, being that it has accepted “modernity” (which is only the name to contemporary western thought and actions, even if horribly oppressive). “Liberal” judaism has accepted class domination, colonialism and so on just as much as other branches of judaism, if not more, which is not a surprise, since the jewish populations which tended to adopt “jewish liberalism” were those closest to privileged populations in the west in social class, taste, customs etc.
I don’t see how this supposedly confirms Atzmon’s vision of the world which is essentialist by nature, simplistic (he doesn’t make a big difference between, say the Talmudic, the medieval and the contemporary eras in jewish thought) and assimilationist (judaism is evil by nature and jews should just become ordinary white westerners, loyal to their respective Nation States). The birth of colonialism (and it’s historical follow-up, neocolonialism) is not the product of jewish social organization and jewish traditions (which is basically what Atzmon, who has never done research in his life, keeps talking about). Colonialism was born when the spanish conquered parts of the Americas. This was the first historical form of colonialism, very distinct from other forms of conquest. It’s historical genesis has to be found, among other things, in the “reconquista” of Al Andalus and the expulsion of the jewish and muslim populations. It first used a modified version of catholicism to justify itself (the Valladolid controversy) and later, as colonialism was adopted by other European powers, started to use the language of “modernity” and “science” for justification.
This is unrelated to Talmudic or Medieval Jewish thought. But of course Atzmon needs to find something to cater to his antisemitic and white-supremacist friends (such as Alain Soral, from France), who generally do not give a fuck about Palestinians nor about the dignity of third world populations.
