Layla points me the way to The Israeli Anti-Semitic Cartoons Contest. The cartoons are not only hilarious, but they teach awesome lessons about the value of liberty and self-directed criticism. These anti-Jewish cartoons drawn by Jews show that if you forbid an idea, it only adds cachet and allure to it; however, if you not only permit but confront and roll around in an idea for a while, you can own it and even take away its power by its exposure to the light of day.
This is only my sense as a non-Jewish reader, but it seems to me that these cartoons, by revelling in anti-Jewish sentiment, completely deflate any sense of righteous anti-Jewish prejudice that a person might have. Interesting how that works.
