Why do we talk around the opinions of natives so much on these forums? Martin is a German in Germany, or at least a person living there. No one has responded to him directly. I see the forum ignoring natives on the much more minor subject for how tourist should dress too. People on the ground know. From a distance we can only guess.
If the German government is repressing news of real dangers for political reasons, that is travel news we should be paying attention to. Mass sexual harassment and rape is a frightening prospect. Mass sexual harassment and rape where the government in intent on carpeting it over is much, much, more so.
As the news comes out, the victims were women between 18 and 30 (plus a few white men who defended them) and the perpetrators were men of African and Middle Eastern decent between 16 and 35, most legal residents of German or even citizens but many illegal immigrants. Theft was the primary object. Sexual assault appears to be only an added bonus and a distraction. Fire crackers were used in the same way. That new in Germany and what's new in Germany is cultural (not racial, cultural). I doubt the women's skin color had much if anything to do with it. This kind of rape happens to brown women in the Middle East and Africa. It's cultural. If Germany doesn't address the cultural issues (let alone if it pretends they don't exist) things will get worse.
Right now, as a plump (if still pretty) woman in her 50s, I don't see myself as a victim of this kind of rape. I have two daughters, who will be 17 and 19 when we arrive in Munich and Cologne this summer. For them I worry. I think we will all be fine, but I wouldn't take my girls out late at night or to a beer festival for anything. My PCness does not extend to my girl's safety.
To be clear though, this is not paranoia. My 19 year old may travel to Berlin and Brussels on her own and in part on our dime, so I do have some choice in the matter. She's a grownup. I'll send her with advice to be prudent about what time she goes where and on what holiday. I will not tell her to shun German, only to be careful.
But if more covered up news is only revealed by social media, I will think about shunning Germany. Danger from thugs is one thing, danger from thugs when the authorities pretend it isn't happening is much, much, worse.
I have viewed Europe as in many ways safer than the U.S.--- higher risk of pickpocketing (mostly because tourists are more vulnerable) and lower risk in fpr violent crime. But if Europeans ignore and coverup violent crime, that perception will change.
