Ah, the myth of the uncontrollable male libido. When my DH and I went walking in Pakistan some years ago, I, like every single other Pakistani woman I saw, dressed modestly.
But, even though I was wearing an ankle length skirt, coat, gloves, big shawl over my head, no skin showing, head down, no eye contact etc, I had to have my brother-in-law walk directly behind me on 'bottom duty' otherwise random men in the street were continually pinching my bum/trying to grope me. Grim.
So, no, not a women's (or children's) modesty issue - how dare IK victim blame - but certainly an appalling male sense of entitlement and male sexual violence problem.
