I don't think the cradle of religious cults, Hollyweird and the Gay Rights and pro-abort movements became that way after WWII because of immigration. Its just that the children of immigrants (Hispanic AND Asian) have joined forces with the socially liberal whites to dominate the state, and the square defense industry workers in SoCal are no longer there as a counterbalance.
Religious cults are not a major threat to this country. I agree with you that Hollywood is out of control, as is the gay rights movement. But c'mon, you can't blame all of California for those elements.
Illegal immigration has truly turned this state into a sh_thole, and you are correct that the newcomers are used as tools of the manipulators. But to just cast aspersions toward California as if to say "good riddens" is not constructive; indeed it's *destructive* with regard to trying to fix the problems. We are all in this together- we should hang together or we will hang separately, imo.
