Controversial websites GeenStijl and Powned definitely make use of Islamophobic language and may play a part in the rising anti-Muslim sentiment in the Netherlands, University of Amsterdam researcher Dr. Ineke van der Valk said to NPO Radio 1.
Van der Valk has been researching discrimination against Muslims for years. This year she analyzed blogs posted by GeenStijl and Powned since their inception, in 2003 and 2013 respectively, until the end of 2015. In total she found 18 thousand articles about Muslims or Islam and 260 thousand comments on the matter.
The websites often frame Muslims and Islam as political or cultural threats, according to Van der Valk's analysis. On both sites the image of Muslims and Islam are solely negative.
