Colossus, I disagree with quite a lot of what you said (though possibly also agree with some). I've been building up to a rant for some days now, so what follows may be more intemperate than is called for. Also, I have a stack of other things to do tonight and for the next few days, so I'm only responding partially.
So, one of the things you said is this:
Personally, I think they need to re-word the Quran to make it damn clear that killing any people is not what your God wants.
The probability that "they" will reword the Quran is about the same as the probability that "they" will reword the Bible, and for many of the same reasons. In particular, I think the Quran is already about as clear and firm on the importance of not killing people as the Bible is - and yet members of both religions violate that rule every day. Al Qaeda, IS, Boko Haram etc. are killing people now; the IRA (whose members were at least nominally Christian) killed people fairly steadily between about 1970 and 1995. At one stage, for example, the IRA had a particular fondness for bombing pubs in and around London - not so different from what IS did in Paris.
More generally, there are, apparently, 1.6
billion Moslems around the world - not very different from the number of Christians, and rather larger than the total citizenship of the "first world" countries. The total number of IS/al Qaeda/Boko Haram/etc. members is 1 or 2 in a
million. So the members of these organisations are no more representative of Islam than the IRA was representative of the UK, or of Christianity. Indeed, IS and others are engaged in a war
against other Moslems, as witness the recent bombings in Beirut and Baghdad. Blaming "Islam" for the faults of terrorist groups blinds us to the true nature of the situation, must surely be seen as insulting by the vast majority of Moslems, and is very probably playing into the hands of the terrorists in stoking the sense of injustice felt by peaceful Moslems against "the West".
