Islam.... Women Can't Look After Themselves?

Because men will use and abuse them in that culture... if they are alone.

"This is what my grandmother had meant when she warned me: if you are a Somali woman alone, you are like a piece of sheep fat in the sun. Ants and insects crawl all over you, and you cannot move or hide; you will be eaten and melted until nothing is left but a thin smear of grease. And she also warned us that if this happened, it would be our fault."
(Ayaan Hirsi Ali. Infidel)
