Ayaan Hirsi Ali sees Islam as incompatible with Western values, at least in its present form. She advocates the values of 'Enlightenment liberalism', including secularism and equality of women. For her, the burqa or chador are both a symbol of religious obscurantism and the oppression of women. Western Enlightenment values, in her view, require prohibition, regardless of whether a woman has freely chosen Islamic dress. Islamic dress is also seen as a symbol of the existence of parallel societies, and the failure of integration: in 2006 British Prime Minister Tony Blair described it as a "mark of separation". Visible symbols of a non-Christian culture conflict with the national identity in European states, which assumes a shared (non-religious) culture. Proposals for a ban may be linked to other related cultural prohibitions: the Dutch politician Geert Wilders proposed a ban on hijabs, in Islamic schools, in new mosques, and in non-western immigration.
