Of course we in Europe also have epidemic, structural sexual violence. Violence is always the dark core of dominance. The men who are now coming to us from Islamic cultural circles are, of course, shaped by conditions there, which are still much more antiquated than here. That's a problem that we have ignored for far too long. In the name of a false tolerance, we have accepted that women are kept at home like prisoners and are forcibly married.

I can't just go up to people standing in the snow at the German-Austrian border and ask them: "Are you an Islamist?" When people flee to us from war zones, we first have to help. But we also have to be quick to look very closely at who it is that is coming.

If I read the Bible, I can also find a few harsh verdicts. Every religion can be abused. We're not talking here about religion and faith. We are talking about the politicization of Islam, and, by the way, it is first and foremost exerting pressure on the majority of peaceful Muslims who live here in Germany.

People aren't stupid. They saw what was happening at the Cologne central station. A lawless space was created in the middle of a city of over a million. That has to be addressed and it has to be done so in a sober-minded way.

But if we keep denying that there are problems with some male immigrants, then we will just drive the people into the arms of the right-wing populists. Without the ignorance or the trivialization on the part of all the political parties, there would be no Pegida or Alternative for Germany.

But when you only speak using generalizations, you run the danger of denying the specific. In recent decades, millions of people have come to us from cultural groups within which women have absolutely no rights. They do not have a voice of their own and they are totally dependent on their fathers, brothers or husbands. That applies to North Africa and that applies to large parts of the Middle East. It isn't always linked to Islam.

Mastery of the German language and the acceptance of our legal system has to become part of the criteria for naturalization.
