I think in KLS's very first PomPress book, MY SCRAPBOOK MEMORIES (the original edition, not the revision), she mentioned a kind of pamphlet that some church or religious (Christian) group circulated about how DS was teaching kids Satanism. They were fighting to get it off the air.
I think that back in the 1960s, this kind of thing was never taken seriously by the mass media. Times have certainly changed.
