IANAEuropean. But, it has been observed that in Europe men of Middle Eastern extraction have subjected European women to sexual assault and harassment at much higher rates than men of a local background, causing women to feel unsafe in contexts that previously did not feel unsafe. The implicit claim, I think, was that this is the cause of the decline of nude beaches.

I have no knowledge of this being the case, although I do stand by the fact that a disparity in rates of sexual abuse by men of different ethnic groups exists.

This is, of course, the sort of topic that is unlikely to be discussed honestly without the protection of anonymity, and even then many people, particularly women, have ideological beliefs that deny or excuse the above and would prevent them from expressing agreement other than to blame "men" in general.
