Why do kids think its funny

One thing I don't get is why kids at school think it's so funny to make fun of the Jews. Seriously? why is that funny? At all? It's not. Remember, Jesus was Jewish. Also, just because South Park did it doesn't make it ok. This is what happens when you let immature 13 year olds watch South Park. Its a social commentary stupid. Its COM-EDY. SAT-IRE. They don't seem the understand the subtleness, and also happen to watch family guy and The new Simpson's, the one that sucks. I doubt they could distinguish a Jewish person from any other religion, Nathan confused a Jew and a Muslim. Its not funny. Hitler would probably be proud of these immature morons.
