Family Guy Controversy

Over the weekend i was watching tv, and I noticed that the newest episode of family guy was on. In this episide, Stewie and Brian get sent back in time to Germany during the time of World War II. While trying to escape, they steal nazi uniforms and when they appear for the first time in them, stewie looks down at his near the swastika ahd just when audiences think he's going to react about that, instead he lifts the collar of his jacket and there is a McCain Palin button on the jacket in which he reacts "huh that's wierd." Personally I thought it was hilarious with the upcoming election because family guy is known to stick little jokes here and there with something big that is going on in the world. Apparently the media didn't think it too funny because there have been many news articles on the web saying that it is offensive and saything that the makers of family guy are implying that nazi's would have supported McCain. I don't understand why people try and blow these things way out of proportion?
