i think, and this is just me of course...i'd play "stupid".
that was an interesting story...what's that gotta do with us?
not knowing your specific situation and the things you may have said to their "sheeple", i couldn't give you guidance and frankly...i dunno how they'd respond being as i dunno your family, but for mine i'd play stupid and have them spell everything out to a t and question every single little thing until they give up.
allegories/illustrations...sigh. especially ones from a cult.
