I live in one of those states. I have watched my state go from an alright place with affordable housing, good liberal laws, etc to a complete shit show in the last decade. Where I am is beginning to feel more like California every single day. Dramatically more taxes, far more expensive houses, far worse roads, increasing stretched police forces, less personal rights, etc. It's a nightmare. People like me aren't antagonistic because people moved here. We're antagonistic because the same shit that brought you the absurd taxes, expensive houses, poor roads, terrible policing, overbearing politics, etc is being exported en masse by these very same people. The average person living here cannot afford to live here because, according to my realtor friend, majority of home purchases come from Californians and they don't just buy one. Ignoring all else the income asymmetry is causing strife to people who cannot afford to live when the chickens come home to roost.
I live where I live and travel to California so often I more or less live there for several days a week. The only thing great about California is the weather.
It's simple, assimilate or stay over there. You left California for a reason - why bring the garbage to every other state? Your voting is the reason California is a dumpster fire in almost every major metro. Walking down Santa Monica, or almost anywhere in San Francisco smells like human waste. You cannot tell me California is "nice". At least the Californians coming here aren't exporting the smell.
