No, but belief is a powerful thing and can transform the way one experiences the world. For better or worse. Personally, I think leftism could use a bit of spirituality to it with the understanding that each of us live in an objective world but experience it through our own mythology. Learning how ritual works within the confines of science doesn't need to inhibit belief if we'd all understand there's a story living inside of each us which we can interact with through ritual and woo.
