In the show Curb Your Enthusiasm, some might say that Larry David is making fun of Jews and is, therefore, self hating. Others, on the other hand, will claim that he is making fun of self hating Jews, and therefore, relatively less self hating...
If it is funny, I laugh. If it meant to harm Jews, i get upset. It all depends on how many people are so gullible that they believe certain jokes. The best way to be is to laugh, but to be guarded to educate those who don't understand reality.
