It's not really the jokes, its not knowing if they're serious or not. Alot of people will actually speak their minds, but wrap it up in a joke so it gets slipped by. If I said a racist white joke to you, but you knew I was a racist you would take it differently. And sometimes it crosses the line from jokes to just flat out offensive. Most of family guy's jokes are like that, but they're extremly funny so I just ignore it.
