While anti-Zionism is indeed antisemitism, anti-Zionism is much more socially acceptable than classic antisemitism. The result is that many anti-Zionist activists can embed historic antisemitic tropes in their criticism of Israel without significant pushback

accusing “Zionists,” or anyone who supports the existence of the State of Israel, of behavior commonly associated with age-old tropes about Jews (such as greed, bloodthirstiness and power) is antisemitic. Additionally, this rhetoric villainizes the vast majority of Jews around the world who identify with Zionism or feel a connection or kinship with Israel
