I can understand in a modern scociety that a Burqa presents problems,a Hijab allows identification for security and legal reasons while still maintaining modesty there is no religious reason for more.
Western women are required to dress modestly in most Islamic countires, if people chose to live in a non islamic county they should acept that they will live by different rules.
If after all islamic women in france demand the right to wear a burqa because it is traditional in saudi arabia would it not be equally fair for french women to bathe toppless in saudia arabia, because it is their custom?
