As for the supposed "controversial metaphysical positions", that's irrelevant. We cannot talk about Spirituality in any meaningful context unless we assume that physicalism (materialism) is wrong. Whether or not it is doesn't matter. In the context of the article, we must assume that it is. 

 :As for being a fringe topic, nothing could be further from the truth. Based on the amount of religious people in the world, this article eaisily makes the test for being a topic worthy of serious analysis based on the definition of the word in religion. That's not even counting the discussion of "spiritual rather than religious", the adherants of which subject seem to be growing. 

 :In short, for the points listed above, and since you seem to be the only one with any points on the subject, I'm removing the NPOV template.
