There is a serious problem in that many people downplay the danger of radical Islam which controls many nations and has been adopted by a great number of people. It shouldn't be scary to say that radical Islam is a major and serious problem in the world that should be tackled. Not to make more of Warbler's statement than he intended, but it doesn't matter if most members of a group don't want to take over the world or install Islamic law everywhere. We see how Islamists took over Egypt, for example.
An instructive article, from the National Review. The magazine (despite being severely conservative) doesn't fall into a trap of blaming the Swedish riots on Islam. It blames the Swedes for creating a kind of permanent benign cultural segregation by virtue of their generosity and aloofness (I want to go there so bad now).
