Women in the Islamic societies, compared with the women in the other contemporary societies, are much more restricted and oppressed. They have no equal rights with men, and are considered as second class citizens, must obey their husbands or another male figure, have to cover themselves so that they can not be seen by another man, are very often beaten up and that is not considered as violence but more like method for discipline, they are not allowed to make independent choices for themselves. All of this is the total opposite of what is happening in the other modern day societies where the women have the same (in some places even more) rights as men, and can organize their lives independently by their own interests.
