If you ban it, you have to ban everything else  If one form of religious symbolism is banned, it would be difficult to justify not banning others. If the government considers face coverings which would be seen as an attack on Muslims (while only a small minority of Muslim women wear them, they are not popular in other faiths apart from for specific uses). If the motive for such a ban is integration and uniformity, items such as the Sikh turban and potentially the Christian cross should be banned as well.
