The current tendencies of this nation and much of our population are troublesome in several respects:
Immigration: Inability to assimilate as fast as immigration is being allowed, inviting excessive and violent cultural change in the coming years; disregard for the law by not enforcing the immigration standards we have.
Cult of "cultural diversity" and "tolerance": Belief that anyones values, culture, beliefs, religion, and behaviors are as good as, if not superior, to our own - being "tolerant" to the point of self-destruction.
Ignorance about the breadth and intent of radical Islam: What proportion of the 1.3 billion Muslims in the world would like to control our nation and dictate their religious standards to the rest of our population?
Lack of defenses for the most likely violent threats to our political system, economy, and infrastructure.
