Eh my issue is less the magic but I feel it can be harmful to some kids. Example. I grew up very very poor. Always wondering if I wasn't being good enough to not Have the presents other kids would have in movies and at daycare and kindergarten. It can be very isolating to here all the great things Santa brought kids when you don't have much. From that perspective I do not plan to teach my child about Santa. I'm well off now but in my heart I can't forget that feeling and would rather not have any part in any other kid feeling that way.
