Carol, all I wanted to show by way of the survey was that although the great majority of Muslims are good peaceful people, there is a small but significant number who are not.

"Just under a third of Muslim students polled (32%) said killing in the name of religion can be justified – the majority of these said killing could be justified if the religion was under attack, and 4% of all respondents supported killing in order to promote and preserve that religion.
- 60% of active members of campus Islamic societies said killing in the name of religion can be justified. By contrast, only 2% of non-Muslims agreed."http://www.socialcohesion.co.uk/files/1231525079_2.pdf

I cited also the fact that Muslims react more violently to perceived insults to their religion.
