If you're wondering about the all the bukkyô information on a shintô FaceBook page, please remember that this is a minzoku shintô page.

As such, it is not "pure" shintô, whatever that may be. And it certainly isn't ancient shintô; it is instead the current practices engaged in by one of today's minzoku shintô practitioners.

minzoku shintô is a syncretic mixture of shintô, dôkyô, bukkyô, jukyô, folk magic, divination, shamanism, spirit possession, and ancient local traditions.

Further, that syncretic mixture varies from location to location. In fact, it varies from one pratitioner to the next. Familes tend to have a core set of practices, but each family member also has their own set of practices that are unique to them.
