Religion does not justify one to supposedly fly planes into buildings, nor does it justify a gruesome Crusade. One that follows blindly has no excuse, as at any moment if they lift the veil from their eyes they may see how they have been deluded.

Except, I'm open to Islam to being the "One true faith" as much as I am Catholicism or Judaism or there being no underlying plan or working, and everything just is, or perhaps this reality is the absence of existence.

I can't verify anything for certain, but I do know for a fact that religious groups have conflicts which result in unfavorable outcomes, ones that the world could do without. That is why I presume a world without dogmatism, whether it be from Jews or Scientists, would be closer to an ideal than our currently religiously diverse one.
