Those wacky muslims, they were born "furious" and seem cursed to forever remain so.
Do they even have a concept of happiness?
Hapiness on this earth is forbidden. No joy. No sex. No music. No dancing. No laughter. No forgiveness.
Only a lifetime of sore knees worshipping a false prophet and a false god. Then you die & find out it was all for nothing.
No wonder these knuckle-dragging troglodytes are pissed off at the world.
