Who said they are non-combatants?
The 'peaceful' muslims aren't organizing into brigades and enlisting in the army. They aren't holding rallies. They aren't outing terrorists in their ranks.
They ARE donating money to the war effort, and to keep madras' open.
Meanwhile they are targeting office buildings and subways where they are killing conservatives that are for the war, and liberals who are stridently against the war alike.
I think politicians calling for the vaporization of Mecca, and the support for just such politicians are EXACTLY the moment of pause that every muslim needs at this point.
It's time to put pressure on Muslims to out their criminals. Publishing polls that show a broad support for the vaporization of Mecca isn't a bad start. Most enemies believe we are soft, stupid, and largely to selfish to care.
The destruction of Mecca is not a deterrent to terrorists, nor would it make Muslims more likely to become informants to the people who destroyed their holy city.
