Banning the burqa in France has nothing to do with the "beauty of Islam" it only has to do with the comfort of citizens.
The French people are not comfortable walking around with people who they don't even know what they have under the burqa.
It is THEIR country,you do not go to someone's else country and impose your rules.
That being said, I believe the ones who wear burqa in someone's country and make them uncomfortable are naive and selfish.
