My theory on all this recent Xenophobia

[Mister Agenda]

Or perhaps it's a conscious effort to keep terrorists out of our country by people who don't want to see loved ones blown up, or run over, or stabbed, or shot.

The USA is the wrong country for those people. They can go to nearly any other first world country to be at less risk of those things.

Perhaps this is a subconscious effort on Evangelical Christians to fight off another religion in which they feel that is a threat to their religion. Threat as in becoming larger than Christianity. After all, Islam is going to surpass Christianity in the coming years. This is also a theory that has been explored when it comes to race relations in America. Whites feel that they are losing the power, and want to do whatever they possibly can to remain in power. Now add White-Christians into this mix.

Islam may become a majority religion globally 'if this goes on ™', but not in the USA. If this is the root of their fear, it's an irrational one. Even extrapolating out a hundred years, it doesn't happen in the USA. And extrapolating further than a hundred years is very dicey. When it comes to social trends, sooner or later 'this stops going on'.
