Family Guy Forum

Family Guy has received a lot of criticism for being overly offensive when it comes to minorities and other sensitive issues. For instance they came under fire for making jokes about the prophet of Islam about a year ago. However I know they are doing it strictly for fun, so I don't believe it is all as bad as people make it out to be. It’s one of the reasons why the show is good. Not to mention funny.
Does anybody find family guy to cross the line ever?
