Muslim girls and women are murdered for honor in both the Western world and elsewhere for refusing to wearing the hijab or for not wearing it strictly. Allegations of unacceptable "Westernization" of a Muslim woman accounted for 71% of the justifications of honor killings in Europe. A 2013 study by Wissenschaftszentrum Berlin für Sozialforschung (WZB) found that Islamic fundamentalism was widespread among Muslims in Europe. The study conducted a poll among Turkish immgrants to six European countries: Germany, France, the Netherlands, Belgium, Austria and Sweden. In the first four countries also Moroccan immigrants were interviewed. Fundamentalism was defined as: the belief that believers should return to the eternal and unchangeable rules laid down in the past; that these rules allow only one interpretation and are binding for all believers; and that religious rules have priority over secular laws. Two thirds of Muslims the majority responded that religious rules are more important than civil laws and three quarters rejecting religious pluralism within Islam. Of the respondents, 44% agreed to all three statements. Almost 60% responded that Muslims should return to the roots of Islam, 75% thought there was only one possible interpretation of the Quran. The conclusion was that religious fundamentalism is much more prevalent among European Muslims than among Christian natives. Perceived discrimination is a marginal predictor of religious fundamentalism. The perception that Western governments are inherently hostile towards Islam as a source of identity is prevailing among some European Muslims. However, a recent study shows that this perception significantly declined after the emergence of ISIS, particularly among the youth, and highly educated European Muslims. The difference between countries defies a "reactive religious fundamentalism", where fundamentalism is viewed as a reaction against lacking rights and privileges for Muslims. Instead, it was found that Belgium which has comparatively generous policies towards Muslims and immigrants in general also had a relatively high level of fundamentalism. France and Germany which have restricitive policies had lower levels of fundamentalism. In 2017, the EU Counter-terrorism Coordinator Gilles de Kerchove stated in an interview that there were more than radicals and jihadists in Europe. In 2016, French authorities stated that of the individuals on the list of security threats belong to Islamist movements. In the United Kingdom, authorities estimate that jihadists reside in the country, of which about 3000 are actively monitored. In 2017, German authorities estimated that there were more than militant salafists in the country. The extent of negative attitudes towards Muslims varies across different parts of Europe. The European Monitoring Centre on Racism and Xenophobia reports that the Muslim population tends to suffer Islamophobia all over Europe, although the perceptions and views of Muslims may vary.
