Personally, I disagree with the notion that anti-Semitism can be explained, justified, or understood in light of Israel’s actions. But if you think an academic should be hiredfired for saying something like that, you would have had to have been prepared, back in 2002, to fire Nathan Glazer for saying just that at a conference at NYU:
Nathan Glazer, the well-known Harvard University sociologist sometimes associated with neoconservatism, suggested that whereas historically antisemitism was rooted in “illusionary” beliefs about Jews, today’s antisemitism is often a reaction to Israeli actions. And he said that such “hostility can be reduced and moderated by [Israel's] policies.”
Glazer, as I recall, said considerably more than that. Among other things he said that since Israel claims to speak in the name of all Jews across the globe, its defenders should not be surprised when its enemies apply that claim to all Jews and begin opposing them as Jews.
