In France and Turkey, the emphasis is on the secular nature of the state, and the symbolic nature of the Islamic dress. In Turkey, bans apply at state institutions (courts, civil service) and in state-funded education. In 2004, France passed a law banning "symbols or clothes through which students conspicuously display their religious affiliation" (including hijab) in public primary schools, middle schools, and secondary schools, but this law does not concern universities (in French universities, applicable legislation grants students freedom of expression as long as public order is preserved). These bans also cover Islamic headscarves, which in some other countries are seen as less controversial, although law court staff in the Netherlands are also forbidden to wear Islamic headscarves on grounds of 'state neutrality'. An apparently less politicized argument is that in specific professions (teaching), a ban on "veils" (niqab) is justified, since face-to-face communication and eye contact is required. This argument has featured prominently in judgements in Britain and the Netherlands, after students or teachers were banned from wearing face-covering clothing. Public and political response to such prohibition proposals is complex, since by definition they mean that the government decides on individual clothing. Some non-Muslims, who would not be affected by a ban, see it as an issue of civil liberties, as a slippery slope leading to further restrictions on private life. A public opinion poll in London showed that 75 percent of Londoners support "the right of all persons to dress in accordance with their religious beliefs". In another poll in the United Kingdom by Ipsos MORI, 61 percent agreed that "Muslim women are segregating themselves" by wearing a veil, yet 77 percent thought they should have the right to wear it.
