While I appreciate the distinction, the point still stands: fetishization is something that humans do, and science, while imperfect, stands on a foundation that is entirely unlike that of religion.

The definition and history of scientism is also more complex than "basically a religion".

Meanwhile, a large and growing group of people truly believe that science is religion in a very literal sense, and they're using that belief to reject the reality of climate change, peddle anti-vaccine viewpoints, etc, and that has nothing to do with scientism.
