Take it easy chief. Parts, yes. All, no. Parts of the Northeast are a cesspool too.
You're in Virginia, aren't you? I make jokes about "the south" being anything south of NY, but in this case, I'm talking about the deep south. Louisiana, Arkansas, Mississippi. And even then, just where it isn't urban.
As for the Northeast, you're absolutely right. Massachusetts, apart from being home to the most detestable teams in the country, is effectively Alabama. Calling them Massholes isn't just a joke.
