The same can certainly be said for Californians. Native Californians once upon a time had the reputation of being laid back, down to earth and pretty friendly. Actually the natives still do, but it's the majority of the transplants (and their offspring) that have become rude and obnoxious. California used to be conservative (remember "Reagan Country?") but the rude, arrogant and obnoxious liberals totally infested the state, and now it is a huge dump. (gee, imagine that).
Once, a long time ago, California had a reputation of having the most courteous drivers in the country. Uh uh, no more. They all drive like freaks now. And they have had freeway shootings now, that was totally unheard of when I was learning to drive in the late 70's.
So I finally escaped California about 10 years ago to a nearby (conservative) state, because I loved all the people here. They were nice, friendly, and down to earth. 10 years later, it's slowly getting rude, obnoxious, along with the rude drivers and more and more vocal arrogant liberal attitudes!
(Help!!)
Soon, there isn't going to be any place left to go. You have my condoleneces.
