Simple sweetie,
It's based on fear, insecurity and the need for total control (gee, don't we have a religion that we're fighting that feels that way).
A man marrying a woman who has experience can be found lacking, or failing. She can look him in the eye and say "I deserve better...I've had better".
It appears that there are a LOT of little boys on this thread; little boys who hate and fear women and yes, who look a lot like the Taliban.
