"Contributors bickering among themselves doesn't alter the fact that the savages who are collectively known as Islamic State would have, eventually, gained arms from somewhere"
Yes - of course the could, but when the two largest arms traders on the planet are happily trading arms with Terrorist states and feudal despots - especially ones who support groups like Isis, doesn't the job of arming themselves become that much easier?
As for your comments on Islam - religions are religions anywhere yo go and will do whatever they are allowed to get away in pursuit of their own particular product - the only thing that differentiate one from the other is opportunity.
