" Calling a prejudice “polite” does not in any way lessen its significance. In fact, in some respects the polite form of prejudice—irrespective of whom it is directed at—is more insidious than the overt, unapologetic, easily identifiable kind. Polite antisemitism is easily camouflaged; it’s subtle and allusive. And when it’s exposed for what it is, people who are not clued in to these types of slurs may be appeased by the polite antisemite’s very polite—and, more often than not, highly unsatisfactory—“apology.
