World Values Survey respondents in 13 European countries and the United States were asked the following question: "Terrorism is everyday news. In principle, most people are against it, but there is still room for differences of opinion. Which of these two statements do you tend to agree with? A) There may be certain circumstances where terrorism is justified; B) Terrorism for whatever motive must always be condemned."
Of those who answered the question, here are the percentages who responded "A" by religion:
Percent saying terrorism may be justified (sample size = 14,566)
Total sample 14.9
Almost half of Muslims feel that terrorism can be acceptable--a rate that is more than three times that of the total sample. Sympathy for terrorists appears to be common among Muslims living in Western countries. (Warning: there are only 21 Muslims in the sample).
