The role of Muslims in the current conflicts

[abaris]

They don't just use the same book.  Beyond the quran the sunni and shia religions also follow hadith, they differ on which of these hadith books they follow, which they find reliable and so on.

That's understood.

Doesn't change the fact, you're playing the no true scottsman here. The radicals see themselves as muslims winning paradise for their efforts. They are muslims. And you saying they aren't is as stupid as any christian or jew claiming their radicals don't get the right message. The message is there, in all the scriptures and it only depends on the individual, their upbringing and environment how they interpret it. And please, don't argue, the Qran hasn't got passages on killiing infidels. Which, in many cases, the radicals view as fellow muslims.
