Context should also be kept on California. While people like to see spreading Californians as the problem with places like Colorado, and there is validity in that, California was one of the more conservative states for most of its history.
Even though San Francisco became a bastion of drugs and alternative lifestyles in the 1960s most of the rest of the state was rather conservative and pro firearm and self defense until the 1980s.
A good majority of the people who changed California for the worst were actually people from other states.
This did include the percentage trying to live lifestyles that would have been deemed unacceptable elsewhere because people kept to themselves in California more and were less inclined to impose morals and standards of living on neighbors (ironic now). That in turn meant California got a lot of the less grounded people.
In fact that was the problem, a large influx of people that wanted to escape where they were from.
A lot of the individuals were from places like the midwest and Chicago area as that was the easiest route to come to California from and as a result more were likely to have family in boht locations who had previously gone that route since it was a prime 20th century migration route.
Many came along route 66 that went from Chicago to Los Angeles and was the prime route other Americans migrated to California for decades. And while others like those during the dust bowl came along that route, the biggest population density to contribute to California on that route was from Chicago.
So you could actually blame Illinois.
So the strange post 60s San Francisco crowd combined with the changing Los Angeles crowd to dominate the politics of the state and change things in a bad way from the 1980s on.
Prior CA actually had better self defense laws for example than the majority of the nation. Castle doctrine and no duty to retreat in the home, and a presumption an intruder is a lethal threat and justification for lethal force going back over a century in California.
Ability to carry concealed or openly on private property, your private business, or your home, no permit required.
Many states have since caught up and surpassed California, but that is a recent thing, as now California now gains more and more restrictions.
