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

We also can't be naïve when it comes to the refugees. Men who commit violence should of course be deported to their countries of origin. We already have enough problems here and we don't need to import anymore.

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.

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.

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.
