my advice to anyone talking about antisemitism and jews is to read Kevin MacDonald first. Antisemitism is basically a reaction to jewish behavior. Sometimes its violent overreaction but a reaction nonetheless. Cicero and Tacitus were antisemites so if you think about it, that what these men said in Roman times were said again in the Middle Ages and then in the 18 to 20th century, then perhaps it means the antisemites were right when they said negative things about jews as a group. You just don't carry stereotypes throughout centuries for no reason.
And MacDonald is honest enough to say that he started out as an admirer of jews and then became an antisemite when he did his research for this third book. It's in the preface :
Preface to the First Paperback Edition of The Culture of Critique: An Evolutionary Analysis of Jewish Involvement in Twentieth-Century Intellectual and Political Movements
