@Lash,
It has become an explosive subject. All politicians are very careful to name the suspects "refugees". They're perpetrators, period. I've never heard of "Taharrush", yet I remember vividly what happened to a female CNN reporter in Egypt where she was stripped of her clothes by a mob of men and sexually violated.
European women, Germans included, aren't used to cover up. They have a very healthy attitude towards their body and they wear skimpy tops and mini skirts. In summer months they sunbathe naked and I don't think they let this incident change their habits.
Since New Years Eve, women are more cautious though, but I would hope that anyone violating women in this manner will be deported at once.
Lash, Germany is quite naive when it comes to immigrants. We are not an immigrant nation, on the contrary, Germany was a homogeneous nation for so many decades, any integration of refugees is difficult to begin with, but the influx of over 800,000 Muslims - predominately men - doesn't come without problems. The current (blue eyed) government doesn't have enough resources to handle all of them. Some small towns had to take in a larger number of refugees that outnumbered the towns people.
There are good refugees and there are bad ones. Fact is, if they want to live in Germany they have to integrate and leave their misogynist traits at home. Angela Merkel promised that anyone disobeying German laws will be deported immediately. Let's hope this doesn't escalate into something bigger. The right wingnuts are too powerful as it is already.
