I'm not really sure what this means. If you are referring to radical Islam, then yes, you can't really ignore their radicalism, and I never said you could. There's certainly a subset of muslims that are radicals. Just like there's a subset of Christians that are radicals, such as those that murder doctors that provide abortions, or radical former members of the US military that bomb a Federal building in Oklahoma City.
Muslim extremists are but one flavor of extremist out there, and attempting to paint all Muslims with the same brush is misguided if not downright bigoted. The fact remains that the vast majority of Muslims in the US (nearly 1% of our population, where Mormons and Jews are at about 2% each) are pretty well integrated into the American mainstream. It's been pretty well documented that many of the reasons for the unrest in Europe have to do with the immigrant poor protesting austerity measures.
I agree partly with these comments, but I think that equalling Muslim extremism with Christian or Jewish extremism is a bit unrealistic.
Islamist extremism has killed tens of thousand of people, most of them catually...Muslim. Islamist extremis, or call it Djihadism is an officail, recognised policy suypported not only by strong aremd groups, but also states. Can't be said for Christian extremists, who are small, limited in numbers, and not supportedby any stte. Even Jewish orthodoxes don't kill, thay limit their "extremism" at throwing fruits to other non religious Jews...
Back to Japan: I repeat that Japan is probably the only country on earth where the risk of a sucicide attack by extremist muslims is nearly Zero.
