Going to have to disagree on the Exorcist responsibility.

What actually sparked Satanic Panic were two things. First was the 1980 publication of the book 'Michelle Remembers' which was a memoir about how someone was terrorized by a satanist cult in victoria, british columbia.

And in 1983, a mother wildly accused a preschool worker of abuse with claims of having witchcraft, underground tunnels and sacrificial rituals.

The Exorcist was in 1973.
