the general assumption is that it is by choice that someone lives in the city they live in. So if someone else makes fun of that city, the one who lives there needs to defend his choice of dwelling place. If he doesn't defend it, the silence says: i'm stupid for living in such a bad/weird place"
now do you understand?

I think every city gets made fun of for something or other. I know a lot of the midwest towns do. And half the time whatever people are saying is true. I don't feel the need to defend my city though.
Now if someone goes along and says something to imply that "all people from Baltimore are..." that might need some defending. You can rarely make such a statement.
