I would go further than that and say that its the Islamic culture as a whole that is to blame. I know, I know, I know, that people will jump up and down and shout that the vast percentage of muslims are normal moderate people ….. I would agree, BUT … I still get the feeling that the Muslim response to terrorism, and especially to the preaching of hate, is luke warm at best. Why? Are these moderate muslims frightened of retribution? Are you telling me that rational attendees of the mosque do not know who is trying to turn the muslim youth, yet how many arrests take place? …….. actually, just who is frightened of whom? Are the muslims scared to take action? Is our judicial set-up scared to take action for fear of upsetting the moderate muslims? What a can of worms! Whats for certain, is that someone has to take action against these people soon, otherwise the vigilantes will take over. And talking about over, don't make the mistake of thinking the ISIS crisis is over. It makes a good soundbite as Trump pulls his people out of there, but once they and the Russians are out, it'll all start again as they come out of hiding, and start to take advantage of the ridiculous tribalism that will never ever leave the middle east.

What an utterly daft thing to say? Not Everyone has a mobile! I know several people who don't own one and do not want one!
