The problem is bringing in large numbers of people who don't share the national culture and values. They are not being assimilated. If you stop bringing such people, the problem will subside. Rape used to a rarity in Scandinavia.
While I agree it is the underlying problem, it is one that will not be corrected soon or quickly. And until it is, women need to be armed, they *have* to be armed.
I advocate being armed and willing to use arms being taught as an essential part of being female around the entire world. “It is what girls do” should be the only justification needed. Girls and women who discover that one of their number is unarmed should loan her a weapon automatically, as certainly as they would loan her a tampon if one was needed and she didn’t have one.
Even in desperately poor countries, girls and women can get a sharp piece of metal or broken glass. Something. Anything. And part and parcel with having it, they must be prepared to use it to inflict injury. Not optionally.
Imperatively.
