One of the examples de Becker uses is a woman who was carrying groceries up the stairs to her apartment when a friendly man offered to help her. She had an immediate twinge of fear (what de Becker calls a "survival signal") and she said, "No thank you." But he insisted and when she hesitated because she didn't want to hurt his feelings, he added a little "typecasting" to set the hook. Typecasting is one method manipulators use to influence people. It's a slight insult designed to cause the victim to prove that the insult doesn't apply to her, and in so doing, she makes herself more vulnerable. Read more about it here.
So she overrode her survival signal and accepted his help. She was raped in her apartment, and if it weren't for the fact that she listened to her second twinge of fear, she would have been murdered that night.
There are orthodox Muslims who are using the same manipulative techniques with non-Muslim countries: Appealing to their kindness and typecasting them by implying that if they prevent Muslim immigration, they're racist Islamophobes. Their goal is to get more Muslims into our non-Muslim countries. And as they gain a greater percentage of the population within our countries, they push for more and more concessions — getting the host culture to yield to Islamic standards one small increment at a time. This is what Raymond Ibrahim calls Islam's rule of numbers.
As their numbers grow, their political power grows. Then politicians can no longer ignore this voting block and the push for concessions grows more insistent and demanding. The country is gradually converted to Islamic law.
Almost every non-Muslim country is on this track, yet still in a position to save itself, and some people within each country — more all the time — are listening to our survival signals.
Our twinges of intuition are correct: Islam swallows up cultures. In the end, nothing is left but Islam. That's just what it does. Our twinge is a gift. A warning. Here's the message, clarified into English: "Don't let them in."
