It's not that much like organised religion, although it has some things in common.
Typical religious irrationalism can take easy refuge in the unprovable, in historic tradition, in the figurative rather than literal. This stuff can do a little bit of that but mostly relies on a lack of judgement and critical reasoning,as well as selective interpretation, so it's much easier to call this stupid. But stupid doesn't simply equal "I am intelligent and would not fall victim".
If you want to compare this to something I think you should be looking at cults, and within that there are better examples than major religions, because for the most part you can be religious without drinking the Kool Aid. Better to look at investment scams or something for a closer parallel.
