Unfortunately they’ll do more damage trying to strip people of their spirituality. Spirituality appear to be a necessary part of the human psyche that will arise on its own even without any kind of religious influences.
In a sense it explains why atheism and global warming belief have become religions in themselves.
There isn’t a single society that has managed to arise without some sort of spirituality or religion. Even remote isolated tribes created religion of some sort or another.
Of their spirituality, or of their religious doctrine? Those are not the same thing.
If someone's spirituality can be better expressed an fulfilled by moving to a different religious affiliation, why is that a problem?
