I'm not bothering to click that because I'm sure he wasn't banned for being Jewish. You're talking about the man who has bragged about preventing a two-state solution.

Oh, lest there be any doubt about Einstein's prescience:

"My awareness of the essential nature of Judaism resists the idea of a Jewish state with borders, an army, and a measure of temporal power, no matter how modest. I am afraid of the inner damage Judaism will sustain—especially from the development of a narrow nationalism within our own ranks, against which we have already had to fight strongly, even without a Jewish state." —Albert Einstein

PS. Decided to click. Netanyahu wasn't banned--certainly not by what appears to be your definition. Being protested is not being banned. The ban was on discussion of the subject, no matter who wanted to discuss it: "The policy put a ban on all Middle East-related activities, and a ban on groups tabling on the first and second floors—for any activities."
