There are extremists, such as the woke-class of progressives, that probably will not change their minds about anything. The same probably goes for the alt-right and QAnon class of Trumpists. The only way for these kinds of people to change their minds is some event or accountability to be had.
The main body of California residents are pretty cool, free loving, hard working, and probably have a lot more in common with you than they'd let on if they knew you were different. If you talk about ideas without using labels (Democrat, Republican, Libertarian, Liberal, Conservative) then their ears and minds are usually open. I observed the same thing with devout conservatives in Texas.
People adapt to the culture that surrounds them and unfortunately the culture in hyper liberal cities has hit rock bottom.
