> One of the primary attributes of any religion is its creed. Each world religion professes a unique set of metaphysical beliefs, which is central to its identity. Anyone who contradicts or denies these beliefs is condemned or cast out as a heretic.
Consider also other aspects of religion (daily practices, restrictions on diet and behaviour, rituals, ceremonies, striving, seeking, penance, purity, community) — they support the central thesis and in other traditions are more central than creed. (See e.g. https://blog.gaijinpot.com/japan-religious-atheist-country/ and comments thereon.)
For that matter, the "scientism" mentioned in the article itself can be either monotheism-inspired (only believe scientific things, believing anything without proof is "unclean", we're better than the ones who came before), or focus more on other aspects (the attitude of discovery and humility, improvement of self and the world, …).
