Iraqi people are shaking their heads when they know that people in the west have sex before marriage and that gay people are getting married. They think that the west is morally corrupt. Different perspective.
I don't think that the Iraqi people have ever forced their social norms on the west.
Personally, I don't care whatever they want to do with themselves. It's their families, their people, their women, their parliament and their social norms. They know what's right and wrong from their own perspective, just like you think you know the right and wrong.
