This is in line with things like the uproar about Barney being demonic. I had one Baptist tell me that the Smurfs were demonic. Saying a little rhyme sounds like a charm or something and this seems to trigger alarms in some people's brains. I guess the candle just clinches it in their minds. If possible, I wouldn't change the candle lighting/nursery rhyme. It would be the easy thing to do but would be giving in to narrow mindedness and stupidity.
