I think that this is a clear proof that the cultural notion behind hiding women's skins to avoid temptation is dangerously flawed.

tl;dr - in liberal countries where there are a lot of temptation, there is 1) a lot of education of what is right and wrong, 2) a lot of emphasis of "freedom within the law" / "do whatever you want as long as it doesn't hurt someone else" 3) a lot of PRACTICE of avoiding temptation 4) erosion of the threshold of arousal, we see so much more porn than any other era in history, the bar for excitement is a little lowered.

Obviously this is no excuse for this behavior, but to prevent it from happening, we need to understand why it's happening. not just say "those barbarian / primitive arabs / muslims" because it has nothing to do with religion or race, it has to do mostly with culture.

Long explanation, and feel free to correct any inaccuracies, I'm not a historian nor an anthropologist

I think that in most societies at some point, being modest and hiding exposed skin happened at some point of time. It exists in Judaism (cover hair, knees, long sleeves), Christianity (think of nuns), Islam.

I assume the main idea was allegedly "good", to avoid temptation, to protect women, protect the family cell (and I'm guessing some will say also to show male dominance over them)

Regardless of the reason, we clearly see that this is flawed.

Why?

In a society where young men never get to see a women in "regular" clothes, they see them as almost we see naked women.

We are grown in a society where even if you see a naked women you know you can't touch her without her consent.

We are taught that no matter what they wear, women (and men) own their own bodies, none of us thinks about going to a nudist beach and start grabbing ass. (well I hope most of us)

But in a society where everyone is covered, there is more reliance on the "if you don't see you are not tempted" than on "let's teach them not to be tempted no matter what".

One society is liberal on the outside (you can dress whatever you like, up to the bikini level I guess...) but strict on the "inside" (you can't act on your urges, you grope a women in public, you are shamed at least, if you rape, your life is practically over)

Another society is very strict on the outside (no temptation) But due to lack of practice of avoiding temptation, once you throw them out of context in a land like Sweden or Denemark, you need to be very naive to think they will just learn by themselves that this is not a meat market.

They need to be simply, re-educated, how? this is something beyond me.
