Well,gud discussion going on,on a very controversial topic.But i would like to add a point in reply to the post of 555.
The discussion is about hijab not about women's right of education and occupation.So even if hijab is causing a hurdle in occupations,it doesnt mean that women stop pursuing knowledge.What u r talking is contrary to the spirit of Islam.Women have an equal of right to educational and occupational opportunities.And how to best reconcile the bridge between the troika of education,occupation and hijab is the topic of discussion.Sticking to the main topic,will make this discussion more clear and fruitful.
