A lot but not all. I live in the north sf bay (born and raised) and am an engineer for a municipality that has seen a big influx in the past 10-years of wealthy bay area/socal types. I (and basically all of my co-workers who mostly grew up here when it was not much different from Oregon) feel the same way you do in Bend about them here in California. It is definitely a class of people who are all about getting up in everyone's business if it is something they do not agree with. I am not sure where they come from but I would definitely say it isn't so much California as a whole, as maybe those accustomed to urban centers moving to more rural areas.
