Should women be allowed to wear a Niqāb, or face veil, to civic ceremonies?

Several Western countries including France, Spain and Canada have proposed laws which would ban Muslim women from wearing a Niqab in public spaces. A niqab is a cloth that covers the face and is worn by some Muslim women in public areas. Currently there is no Niqab ban in Brazil. Proponents argue that the ban infringes on individual rights and prevents people from expressing their religious beliefs. Opponents argue that face-coverings prevent the clear identification of a person, which is both a security risk, and a social hindrance within a society which relies on facial recognition and expression in communication.
