The Media coverage makes this worse because ISIS feeds on the Media coverage. perhaps if the media didn't cover it they would lose interest?
At this point, I don't think they'll stop if we ignore them. There's always social media after all.
This is a wrong strategy of burying our heads in the sand. It's also not fair to the victims to pretend like it didn't happen, like they didn't get killed.
Sadly it seems like the only way to deal with this is the complete separation of the Muslim and Christian cultures. The globalism experiment failed, at least when the cultural difference gap is so huge. Maybe we can try it again in the future, but for now it will be best if we take a few steps back and try to return to the times before globalization.
