And people like that do exist in California, both transplanted and native born (raised by those who moved there). I've been in and passed through rural regions in California that actually felt more like Texas to me. In fact, there are many Californians who want to break away, such as
Jefferson (*)
(* When I was there, and most people are normal, they seemed to have an unusual amount of extremists who distrusted the Man on both the Left and the Right, but definitely a slant for conservatives outside the college towns. One person even painted a Confederate flag on his barn. And according to the wiki link I left there, Donald Trump would've won by a landslide in Jefferson were it separate from California.
And relevant to this thread, I met some religious fundies even crazier than what I was used to in in the rural East Texas Bible Belt, and heard of worse, including a cult that supposedly believed Proctor & Gamble was of the devil and were hiding from it. At the same time, this is where I met some Wiccans, some very feminist, at times to a scary degree, others more like hippies. One of those Wiccans endured death threats from one of the crazy fundies when he found out she was a Wiccan. If I wanted to write fanfic about it, I could easily fit her family in there, though their accent would have me portray them as transplants--but then that show is infamous for bad accents.)
