Sweden is today a country with ethnic, cultural and religious diversity. My aim in this study is to study what view of Islam and Muslims that students at a Catholic school in Stockholm have. The reason why Catholic schools are interesting to study is that previous research has showed that Muslim students around Europe often attend catholic schools as they are regarded as more tolerant towards religion. This study is based on a questionnaire and personal interviews with upper secondary students at the Catholic school in Stockholm. The result is compared with previous research on students of the same age group (12-15 years). The results of the survey show that the majority of students have a positive attitude towards Islam and Muslims, but that there is a small group at the Catholic School who have negative attitude towards Islam and Muslims. The negative attitude increases when it comes to the Muslim’s rights, for example the right to build mosques in Sweden. The results also show that students with parents with higher education are more tolerant than students with parents with no academic education. I have used Mattias Gardell’s definition of Islamophobia to analyze the result from the survey and interview among the students at the Catholic school. When using this definition, we can see that the students have some islamophobic thoughts about Muslims and Islam. The results indicate that the school needs to actively work with this question in a more constructive way. One of my suggestions are that they need to talk more about Islam and Muslims during the lessons so the students gain knowledge about the religion but also create situations where non-Muslims and Muslims meet. In this way, students can integrate with each other. This study only shows the attitudes among the students at this Catholic School.
