I think you are right. There are intersting times ahead for us all. Aside from the occasional high-visibility terrorist attack, the MO for these heathens is to emmigrate into a country, reach a critical mass, begin exerting political pressure, destabilize the society, and then take control. The critical point is when they gain enough influence to mute the opposition (usually through their influence on weak politicians and the PC media). Marxists must indeed be in deep envy.
It is happening in the EU big time right now. They may be starting to wake up, but the socialist PC influence is very well imbedded into their socieities. Will have to see how they respond (study France, England, Germany). Violent crime could become the last straw for them.
However, this scourge is coming our way too! Better get prepared. Main difference is: faced with a steep increase in violent crime perpetrated by radical muslims, the "rank and file" will step in to take care of them. If they think that they are ferocious, they will be very surprised indeed.
You have described the political conditions in California exactly. Thank you.
