MOUNT SINAI - Seasonal semantics are causing a controversy in Mount Sinai, as some residents feel the annual tree-lighting festival should have Christmas in its name. The Mount Sinai Heritage Trust, a local non-profit board that holds the annual festival, says it didn't mean to offend anyone by calling the ceremony a "holiday tree-lighting festival." The group says it was trying to be all-inclusive. Yet residents say the political correctness has gone too far, and they're demanding that the name be changed to include Christmas. Some 150 residents have signed a petition over the issue. The heritage board says it will hand out a survey to ask if people want the name switched. Changes probably won't take effect before this year's festivities, which are scheduled for Sunday.
