Haven't you heard the term "tyranny of the majority"? Kalifornia is caught in a "pure democracy" trap. Entitlements have become so lucrative that people flock to the state to take advantage of them.
There is no way to wrest control of this greedy majority. The representatives, who our Founders expected would be motivated by the highest ideals of human accomplishment, instead pander to the lowest expectation.
Budgets are not passed on time and include deficit spending hidden with smoke and mirrors. The courts allow any liberal joke to go unchallenged. The majority in Kalifornia is getting what it wants, but it will destroy the state.
You have told me to change the state constitution or move. Those are the two priorities in my life now. But when the time comes that I do move, it will probably be the last move. If I move to your state and the majority infringes my rights, what then?
Everything in your post is a legitimate gripe, but it doesn't change the meaning of the Constitution. If the 2nd amendment can be properly enforced (that is, by de-fanging all federal gun-control "laws", including the 1968 act), then it will be considerably harder for states to maintain enforcement of their gun control.
