Bigoted? Ignorant?
I wouldn't be offended in the least if Midwesterners or Southerners or West coasters or Sunbelters or Pacific NWesterners lightly referred to New Englanders or New Yorkers with one of the following blanket generalizations: that we're rude, stubborn, cold, unfriendly, arrogant, liberal, pompous, or any other stereotypes you want to throw out there. What makes this country great is that there actually are regional stereotypes/tendencies, and they ALL have their upsides, downsides, truths, exagerrations, character and all the rest of it. This country enjoys poking fun about itself, and we can celebrate the things that differentiate us.
My mother's from Ireland, and my uncles all say the same thing: "What differentiates Americans from the rest of the world is that they can laugh at each other and criticize each other and themselves without going to war over it. They love each other. They love their differences."
It's one thing to jokingly refer to a region as sappy and simple in a playful way. It's another to call another individual you've never met bigoted and ignorant.
