" The difficulty Corbyn and his associates have in recognizing and acknowledging antisemitism on the left seems to be rooted in their foundational claim that because being a progressive means being opposed to any form of racism, oppression, or group hate—including antisemitism—therefore, by definition, a true progressive cannot be an antisemite. Their claim runs into trouble when they are confronted by progressive compatriots who include blanket statements about Jews in their excoriation of wealthy capitalists who oppress and exploit the poor, who imply that Jews exert undue influence on the media, who deny that Jews can be the victims of race-based hatred in the same way that people of color are, and who include offensive, hate-filled Jewish stereotyping in their criticism of Israeli government policies regarding the Palestinians.
