for me, as a self-identified european pagan, dechristianization means going back to the old ways, before christianity existed - which was the literal project of the renaissance, and it's flowering in the enlightenment.
for you, it might mean chanting at rocks or something.
but, the point is to throw christianity away, part and parcel, not to try to adjust it to fit modernity.
we don't put combustion engines on horses, and we shouldn't try to put science on religion.
