Your analogy is not correct. There is a lot of difference between poetry and life/death situations. You are mixing apples and oranges saying they are the same. Wrongo here!! Now the perfect analogy would be asking if you would teach that James Whitcomb Riley's poem, "Little Orphan Annie" was written to scare children into behaving correctly, or to tell a childhood fantasy about gobblins and ghosts? Both poems, "Night Before Christmas" and "Little Orphan Annie" were written to enhance childrens' fantasies, no more and no less. To make it anything else is not to be tolerated nor accepted by the general public. Hence, your rebuke is not correct.

wrong argument. No children are being taught to ask Little Orphan Annie for Christmas presents. Santa is being taught as a God substitute.
