WHY NOTTTT?

The views of the writer are not always portrayed through the characters. Shows like South Park that make fun of literally everything simply cannot be the views of the writers expressed through the characters. Chances are some of the staff is jewish, the show quite frequently makes fun of jews being cheap and having really bad hair. If the writers seriously felt this way it would create quite a mess in the studio. It is possible outside of south park some of the character's aspects are a reflection of how the writer feels. In fact many of the stereotypes come straight from the writer's mind.
