Sorry, I like my way better, to not live in fear.
Fear is a necessary emotion. It keeps one alive. Lack of fear in face of real dangers is not bravery, it's foolhardiness.
Specifically, with regards to mass migration and Islamization, it's sticking one's head in the sand.
Fear has an important place and I didn't say that I hadn't been afraid. I foolishly worked under a car that was being held up by only by the jack. It started to fall off and the shot of adrenaline that the realization of what was happening is what got me out of danger.
I also know how realizing that people were trying to kill me to sharpen my concentration on the job of trying to kill them. But that fear made it more likely that they would succeed before I did. Fear is irrational because it interferes with rational thought. I am a pilot and I know that fear has no place in the cockpit, it lessens any chance of recovery and results in avoidable accidents, controlled flight into terrain, VFR into IMC, etc.
But I don't see how it is rational to be afraid of an entire group of people because a few of them commit crimes. Extending this logic to all identifiable groups in society would leave you afraid of everyone.
I believe that you are afraid of these people. I just don't understand why.
The Germans, like most developed countries, need immigration to provide workers for their industries to keep their economy growing. It has been this way since the end of the Second World War. Why would they follow your advice and be afraid of these people because you are afraid of them?
That crime in Germany has decreased since the "mass migration" is a fact. Would the Germans consider your fear to be rational when compared against their actual experience?
But you can't explain why you are afraid of these people, other than that some small percentage of them commit crimes and that their ancient holy book encourages terrorism.
But their ancient holy book encourages peace too. This is the way that religion works, it is successful at predicting because it predicts everything, all possibilities.
Only a small percentage of these people are worthy of any rational fear. A much smaller percentage of the migrant population is dangerous than the percentage of native-born gun owning white males in the US.
Are you also afraid of gun owning white males in the US? I am not.
Possibly the biggest problem with fear in society is that it is used to divide people against each other. It divides people into groups against one another, groups that otherwise would be natural allies. In a democratic country, the poor and the middle class vastly outnumber the rich. The rich use fear to divide the poor and the middle class against one another along racial and religious lines and they pit natives against immigrants. This is done by the simplest thing to do, by lying. Explain to me how you know that you are not a victim of this manipulation. That you have escaped these lies and instead your fears are based on facts.
