Want to know what ISIS is up to ? Instead of speculating, just take it from their official magazine - it is right there, explicit. The strategy is called “The extinction of the gray zone” - it is about polarizing western society by eliciting islamophobia: “Muslims in the crusader countries will find themselves driven to abandon their homes for a place to live in the Khilāfah, as the crusaders increase persecution against Muslims living in Western land. [..] Eventually, the gray zone will become extinct and there will be no place for grayish calls and movements. There will only be the camp of īmān versus the camp of kufr”. So, if you want to counter ISIS influence in our society, you know what to do: love each other... Turning to epidermic identity politics won’t help a bit. Even ISIS remarks that our “response is often violently reactionary instead of forward-thinking” - and that is just the way they want it.
