South Park Videos Are Not Right Or Right?

Every person in the world has a religion, Muslim, Jewish, christian. There are dozens of religions. South park, Family Guy and the Clevend show, are just 3 out of hundreds of cartoons that have jokes about religion in it. I don't understand why people make such a big deal about it. Everyone has at lest once made a joke about someone else religion, and plenty of times about they're own. I think that cartoons should be able to make jokes about any religion.
