It's hard for me to connect your example of filling gas in Oregon to being reflexively insulted. Is that how you feel in your car, reflexively offended by Oregonian gas stations before your cultural sensitivity has time to resurface? Again, I have to say that I am sure personal differences are strong here, because I don't feel an uncontrollable bodily urge to jump put and fill up the tank within 140-220ms [1] of arriving at a gas station before my consciousness kicks in and I can make decisions again.

What I found is that there seems to be huge difference in cultures about how offended one can be from language (verbal/non-verbal).
Obviously, perceived threat is a different thing altogether!
