But since the end of the 1970s, at the beginning of the revolution in Iran under Khomenei, we have experienced a politicization of Islam. From the beginning, it had a primary adversary: the emancipation of women. With more men now coming to us from this cultural sphere, and some additionally brutalized by civil wars, this is a problem. We cannot simply ignore it.

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.

We need to finally be proactive in enlightening people from Islamic cultural groups. And this applies to immigrants already here as well as to current refugees. The German constitution stands above the Sharia. Schools need to offer classes on gender equality. You also have to offer an alternative to young men with a penchant for violence.

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.

Human rights are universally valid and indivisible, regardless of culture and religion.

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.
