So you're saying Europe is being invaded and rape is just a part of it? While your at it check out what the Arab troops under French command got up to.
No, I'm saying when large groups of young men are let into an area unchecked, things like that happen. The issue isn't that these people are "rapefugees"; it's that it wasn't properly checked and was akin to a wartime mass occupation of a city.
It was unfortunate, and should be learned from, but it doesn't mean "all refugees are rapists", every bit as much as it didn't mean "all allied soldiers are rapists" in the aforementioned example.
