The Moscow Airport Bombing. I'm going to go out on a limb...

[The Large One]

And the justifiable reason is exactly what ??, I've said on here before and will say it again, unless Islam followers give us a clear and concise insight to their religion then what are we to think ?? One minute its one of peace, the next it's something else. Ask 4 muslims the same question, I guarantee you'll get 4 separate answers Therefore they don't help us understand their ideology. Qatar World Cup, cant wait to see their levels of tolerance. Good luck with that project !!

I don't think you've quite got the hang of this, have you?
