Agree with a lot of what you said here, but I think we need to re-evaluate our idea of what "religion" in modern society.

Simplify religion to a "shared set of core beliefs + principles by a group that reinforces a specific view of the world", shift the focus from theism to cultural homogeny, and you can see the "new religions" forming. We see it on both the right and left, think MAGA/Trumpism or "woke"/anti-racist cultures.

There are tons of similarities between conventional religion and these new cultural belief systems. Religion isn't dying, it's just transforming. At the end of the day people still need a framework to view the world and make sense of things.
