I think she sounds a bit looney, but no worse than a lot of folks around the holidays. And she has a point in that maybe the public schools shouldn't be having lessons about Santa as through he is a real person. She seems pretty religious herself, so I would guess she knows it when she sees it- she asks if we're going to teach about Sanata, why not teach about Jesus as well?
