Thing is I know that most people hear that accent and instantly stereotype them and that's the end of it. Doesn't help that every time the people were saying "He's crazy" they showed them saying that. People at home are going to be saying that as is, don't really need to see the people actually in the show to say it as well.
That said I don't think the guy in the show is doing anything wrong, I'm sure he's just trying to be as informative as he can be, but networks just have to put their spin on everything.
