I live in California...
I can tell you one thing... People up north are more blunt and to the point, they don't take offense in things so quickly. They just tell you to get bent...
Where I am in Virginia people get very offended over everything you say, I can barely talk without someone getting offended.
I believe it's all in the way you were raised and where you live and how you react to certain situations.
I'm hotheaded I go from 0 to 100 and 2.2 seconds... That's a New England thing
I am ashamed that I am a "californian". This place is so backwards it offends me.
I'm very, very good at ticking people off. Sometimes I even do it intentionally!
