There were agnostics and atheists in the Temple, attracted by its socialist goals and Jones’s frequent dismissal of the Bible as racist propaganda.
I, as a neo-Pagan occultist for for decades & now as a atheist may have been interested in Jones for this very same reason.
But at either end of the spectrum, not interested enough to join a cult. I might have gone to a meeting or spoken to someone but I wasn't coven, church or group oriented then & I'm even more reclusive now.
