I don't quite understand this. Jake Delhomme grew up in southwest Louisiana if i'm not mistaken. He speaks with a straight Cajun accent. Not a New Orleans accent. So he's one of ours? The Mannings speak with a normal accent/slightly southern (because of their aforementioned Mississippi roots and because the Garden District was first settled by protestant Americans mostly from the South, not Catholic Creoles or the Italians and Irish and blacks who all give to our New Orleans accent).
So if you're from another part of the state, you're one of ours? But if you're from our city, but you grow up with money and without a thick accent, you're less of a New Orleanian?
Being from Uptown (Broadmoor, not exactly Beverly Hills), i'm often times confused about a certain bias that lingers to this day.
