No one is forced to be a member of any religion, with all its associated customs and inanities. My Irish Grandmother always wore a black lace veil, when she went to Mass and she went every day, but nobody forced her to wear it. My Mother went every Sunday and never wore a veil, ever. But they were both committed Catholics. Both were very strong, independently-minded women, and if either of them had been "instructed" by a man in what they should wear, the men would have been treated to language that the Parish Priest couldn't possibly have condoned.
If some Muslim women feel oppressed than that is an issue for them to sort out. Banning one form of clothing and allowing others isn't going to help that situation at all. Instead, it will just make a lot of smug, white xenophobes feel even more smug that they normally feel and it won't change anything.
I will reiterate that the Charlie Hebdo massacres occurred in a country, that already has anti-burka legislation in place and it completely failed to protect anyone.
