Statements like this really pi$$ me off. What are we supposed to do, just abandon it to the invasion because you don't like it? I think Ronald Reagan would disagree with your assessment.
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.
