So, Alain Finkielkraut was called a Zionist and that has been counted as anti-Semitic. The article is conflating all sorts of things in an attempt to blur the lines and to persuade people incorrectly that being anti right-wing Zionism is being anti-Jew.
Is he or isn't he a right-wing-Zionism supporter? If he is, then he's supporting evil against righteousness. Nobody calling him out for it is necessarily anti-Jew.
Those who are singling him out solely for being Jewish, if any, are obviously stupid.
