Beyond the obvious Cloward-Piven agenda in play throughout most of Europe and the US, open border policies accomplish much more than simply erasing western culture with third-world migrants. The introduction of violent peoples from violent countries and ideologies is a perfect way to generate public hostility and getting them to react in anger. When a government refuses to represent the interests of actual citizens that are under attack by foreign elements the only avenue left to that populace is self defense.

Establishment elites understand very well that their malicious activities are going to generate a vengeful response. Their first measure is to shame the public with accusations of "extremism" when the public fights back. When that doesn't work, the next measure is to use popular riots as an excuse to impose authoritarian controls "in the name of safety."
