Jeffrey Goldberg, in the Atlantic hits the nail on the head, when he writes:
One of the great advantages of being Jewish -- and there are many (we invented both ethical monotheism and whitefish salad, after all) -- is that though there are only about 14 million of us on the whole planet (18 million before World War II, Mr. Galliano), people can't stop talking about us! It is very exciting to be a part of so many different fantasies.
So if you can't get rid of them, ridicule them.
