Unfortunately for too many "Muslims", the hijab has become cultural and not religious. Some girls wear hijab because they fear their parents and their parents make them wear it because they fear their community - nowhere in that equation of fear of people does a love for God enter. It's the same reason you see 6 and 7 year olds in hijab when they don't even understand concepts such as sex or modesty. As long as people do things for other people and not God, this sort of nonsense will happen and people will deviate further from deen and reason.
