Clifford May gets it right.
"Most of the world's Muslims are neither rioting nor calling for the death of the Pontiff. But quite a few may reason that if Christians and Jews haven't the confidence to reject dhimmitude and defend freedom, they would be foolish to stick their necks out. After all, a Muslim who challenges the Islamist Fascists brands himself as an apostate – as deserving of death as any uppity pope."
Some of the folks who comment here are still in denial about the urgency of the threat. Instead, it appears it's more fun to overreact to a political fundraising letter, and accuse Republicans of "scare tactics".
Watch for the Law of Unintended Consequences to work wonders on these folks.
