…by denying liberal principles, Zionism immediately becomes continuous with — rather than contradictory to — the anti-Semitic politics of the sort promoted by the alt-right. The idea that Israel is the Jews’ own ethnic state implies that Jews living outside of it — say, in America or in Europe — enjoy a merely diasporic existence. That is another way of saying that they inhabit a country that is not genuinely their own. Given this logic, it is natural for Zionist and anti-Semitic politicians to find common ideas and interests.
