You are right I think. In fact, it can be very much more extreme. When I moved from the North East of England to the South, some people thought I had 'betrayed' them in some obscure way and one person became very aggressive demanding to know what was wrong with the area. Leaving it was clearly equivalent to finding fault with it in his eyes.
