"soil their trousers at the sight of a headscarf"

They probably don't, but haven't you figured out yet that that's the very reason for the headscarf? To make sure everyone knows that "We are different from you, and we want to make sure you know it?"

Have you ever seen a family where father is modern, kids are modern, but mother looks like she just stepped out of the nineteenth century? Ever ask yourself what is the logic of this? There is no logic; there is only the desire for separatism.

The same applies to many of the world's hairstyles and hats.
