Earlier quoted context omitted.
Why is this pushback being met with cries of racism? Because it's often couched in explicitly racist terms. Shared values should matter more than the color of your skin, and values can (and often are) shared across cultures.
Stop calling people you don't understand racists. These rednecks hate all people who refuse to fit into their culture. They'll hate white NY or CA transplants just as much as they hate Mexicans. Unfortunately actual racism is picking up steam with these folks.
I don't blame them. Nobody who grew up in CO before it was California Lite will tell you that immigration from CA made the place better.
Large amounts of inter-state immigration has in my estimation hurt culture in the destination communities far more than immigrants from a different country, or at least that's the track record so far.
Lewiston Maine vs Portland Maine would be a good example. Lewiston had a bunch of Africans move in and the place has been perfectly fine. Portland had a bunch of MA transplants and it's changed for the worse. It may as well be MA now.
I mean sure, Portland has more money but would you rather have money or your culture?
edit: and I'm wrong because why?
