it also features in the exorcist as the spiritual conduit which allows the demonic possession of the film. so some people who were relatively young and impressionable when it came out maybe freaked a bit and decided to just never conduct that particular experiment.
This is just religious paranoia based on mass corporate marketing lol. Similarly, the concept of “Lilith” being a demonic figure isn’t even part of canonical Christian lore, it was incorporated from other religions/occultist texts in the late 19th century/early-mid 20th century by American evangelists and now suddenly Christians have to fear this random biblical lady as a succubus who will drain your balls
The Ouija Board (along with other types of spirit board) was never intended to be used for the purposes we associate it with today. It was meant for "automatic writing" and people believed they were communicating with their unconscious self. Spiritualists of the late 19th century looked at it and said "no it's ghosts."
People are welcome to their own beliefs about spirit boards. Except for people who look down on others for having superstitons. Those people are assholes.
