Hostility to Israel is partly caused by antisemitism and is also itself a cause of further antisemitism.Oh look, "partly". So "Hostility to Israel is partly caused by antisemitism". Only partly? So what about the other parts of hostility to Israel? Might they be caused by Israel's existence as a racist state based on colonial settlement, ethnic cleansing, segregationist laws and relentless violence towards non-Jewish natives and neighbours of Palestine? Hirsh doesn't say, not in this article anyway.
Hirsh's latest masterpiece also appears on his own Engage website but not on the Israel lobby group BICOM's Fathom website. Maybe he missed the deadline.
