I don't agree with this ban purely from a libertarian standpoint. I believe people should be able to wear whatever they want, the government shouldn't be able to dictate what people can and cannot wear, that's just too authoritarian.
Also what about freedom of religious expression? I'm an athiest and I think women wearing burqas is stupid, but I think religious people should express their religion however they want (as long as it doesn't harm other people), again the governement shouldn't be meddling in peoples lives like this.
Plus is this really a good idea? I mean I can understand that there are some muslim women forced to wear the burqa which is really wrong, but what about the rest who choose to wear it willingly. All I can see this doing is making muslims feel like their being persecuted and targeted, which will only breed contempt for the white majority in this country. At times like this do we really need to create more divisiveness between peope?
