You know what, Castiel? I concede the link point to a reasonable degree, but let me explain. Firstly, I'm not a Muslim, nor am I religious at all. I'm, admittedly, parroting a lot of what some Muslim friends of mine convinced me of. They are indeed amongst those that often say something like "they aren't true Muslims and that's all there is to it".
I've been of two minds, and the one I was siding with here is obvious. I agree that for those nearly 2 billion adherents to properly handle these things, they need to have an open, honest discussion instead of callously ignoring the problem (and, yes, it is an extremely real problem), and that includes accepting and moving forward with what you brought up.
As has been thought of countless times before I'm sure, all religious leaders of the world should perhaps get together and work towards a universal constitution of sorts. That, and no doubt thoroughly recognising and dealing with the complex conditions through which radicalisation forms.
Anyway, I'll be sure and have a conversation with my friends on this again, and from a much better position.
Go ahead and think lesser of me for not being afraid of admitting wrong and growing as a person, I can take it.
