Because the best way to deal with them is warped humor. They exist. We didn’t create their yetzer, but the anti-Semite and the self-hating Jew uses them against us anyway. What’s more, it is not a Jewish idea that being “religious” keeps you from committing crimes. If we didn’t have criminals, there would not be dinei mamanois and dinei nefashois.
So, I say laugh at them and hate the anti-Semites rather than the other way around.
