I personally think using a word like 'spiritual' in
opposition to 'religious' throws a spanner in the works.
Here is a standard dictionary definition of spiritual:

Doesn't really define anything very specific, does it? A person could be an atheist and be interested in definition 5.
'Religions' that tend to be monolithic and controlling usually involve dogma, orthodoxy and orthopraxy. Those three are the villains of the piece as they can stand in for a form of social and personal control. I have no doubt that if one or other form of 'paganism' now rose to the top, it would look the same or at least ACT the same as many of the 'big' religions. It's only because most neo-pagans can't agree on anything for 5 minutes or can't organize a piss-up in a brewery because of this

that as a group, pagans are not just another controlling religion. And mind, I've seen some try. 'Right think' and 'Group Concensus' are alive and well in paganism. After all , a lot of the early christians were just as likely to be sold down the river by one of their own lot as by someone of another religion . And I've seen pagans treated like crap by other pagans - all is not sweetness and light in pagan land either.
Anyone can be 'spiritual' and it means nothing other than how they perceive a particular subjective state or phenomena , IMO. It has no 'value' attached to it in terms of being specially aware or open to extraneous and even undefined phenomenon. One can be in a particular religion or not and still be 'spiritual'.
As far the world and religions go, I think it's the same as the world and politics or the world and economics ( in which said areas big religions have always had an interest as it furthers their cause as well frequently) - once you get large blocks of people believing and acting in concert for some subjectively defined end, there is bound to be trouble.
It's probably that very quality of admitting to diverse experiential paths that keeps pagans from becoming what they would despise.
