The real issue is the behaviour of young men from Islamic nations of North Africa and the Middle East and their view of women in society.
They view a women's role in society in a very different way in their home land as compared to their new home in Europe.
For example, if you report rape in the Middle East, the women who was raped goes to jail for having extramarital sex:

We seem to have two viewpoints of young men from these countries.
1. The Angela Merkel view where they are the nicest people in the world looking for a new opportunity and they deserve a chance because they are refugees and.......
2. Potential terrorists.
There seems to be no in between in these discussions.
This discussion about treatment of women also occurs when they travel the globe.
Females travelling alone are finding the Earth shrinking rapidly:
