Good gravy, I know this one is old, but where did he get his information? Halloween wasn't ever, so far as I'm aware, a time when Druids went around knocking on doors demanding human sacrifices to Satan; they didn't even conceive of such a being as Satan to begin with! Druidic worship was Pagan worship; and while, yes, there may have been human sacrifices, typically they were willing ones, IIRC, that were sacrificed in order to ensure a good harvest the next year. Or at least that was one of the supposed reasons, I think. Regardless, Druids had nothing to do with Satanic worship in any way, shape, or form.
