Ok, saying that religion is not a problem when they're killing in the name of their religion is just ignorant. What about previous muslim caliphates and attempts at it, was religion a problem back then? Was religion a problem during the crusades? People always say shit like that, even with homophobia in these religions:"Religions aren't responsible for their bigotry, the brainwashing and lack of education is." Well guess what? There are many places around the world where people have accepted homosexuality, where these religions haven't been present, just with this kind lf terrorism. Where are the 80 000 South Africans who kill in the name of their religion? Why is terrorism a problem in Indonesia, but not in Hong Kong? Why aren't there any Serbian suicide bombers after the NATO bombings? Why hasn't similar organizations risen up in Vietnam? Where were the Dresden Jihadists?
It's obviously quite clear that these mass-murdering sects are prevalent in muslim countries, maybe that has something to do with only factor that links them together, Islam. Huh? Washabism is not uncommon in the muslim world, especially among some specific places.
Now as for your integration-excuse. In many cases it may be true, but many not. A Swedish newspaper released a list with all "Swedish" ISIS fighters something like 2 years ago. Many of them were highly educated and had studied at university and such. How do they have less going for them than me? I went to school with an Algerian guy and he sympathized heavily with terrorists, he hadn't got his family killed more than you and me. Is
Islam is most definitely responsible, no question about it.
