While I realize that different groups have different traditions, one common understanding, firmly enforced by my Mother, is no Christmas decorations or music before Thanksgiving. She complains loudly when she encounters stores that start the process early as she feels it commercializes the season.
Fortunately she hasn't been able to get out and about since leaving the hospital or she would be thoroughly annoyed by locations that had Christmas merchandise on the shelves before Halloween.
One of those she would be "expelling from the temple" would be a certain terrorist sympathizer
who already has Christmas decorations up and Christmas "gifts" available in a most commercial manner, while claiming to be a defender of the holiday.
Commercial exploitation does not a Christian make.
