Saudis arrest Christian for entering Mecca.

I think we can only interpret this a hostile posture towards the west, though only passive-aggressively.

However, I cede the point, religions have been given the right to be as loony as they wish.

The growing intolerance in some Middle East states is worrisome. How much of a legitimate threat these groups are to the West we obviously can't know. They appear to want to fight each other if we would just get out of their way.

When was the last time a Christian decaptitated someone because he didn't agree with him?

At least in the last several years, the "ability" to decapitate people they disagree with seems to be an exclusively Muslim virtue.
