I tried to find the article in English but the problem is, if you google "gang rape, park, Germany" you get too many different stories to be able to find the right one. There is an additional angle to that story, which is that unfortunately the rapists were "not German born" and therefore I think there was a worry it would become a "far right talking point." So the far right are the only ones talking about it. The problem for me is that the far right are blaming these incidents on the "foreign" values of the men committing the rape - when its really clear on some level the German authorities share those values. So you have (some, not all) immigrants coming into a country with the idea that underage German girls are worthless/are there to be abused/rape isn't a big deal. And the response from Germans is "yes, German girls ARE worthless and absolutely can be abused. Rape isn't a big deal. What's more, we will arrest anyone who is mean to you about this". Its not a failure to integrate into German cultural values - they may be scum but they seem to have picked up the "values" of the German lawmakers fairly quickly.
I don't want to see a rise of the far right in Germany. But if I DID want to see it, I would be doing exactly what German policy makers have done for the past decade.
Also - Germany is a country which has brothels where you can, perfectly legally, pay for "all orifices" deals etc and the women can't refuse. This is very liberal, and very tolerant and progressive. And you can even get a free burger. Yay.
