BOSTON - Boston set off a furor this week when it officially renamed a giant tree erected in a city park a "holiday tree" instead of a "Christmas tree."

The move drew an angry response from Christian conservatives, including evangelist Jerry Falwell who heckled Boston officials and pressed the city to change the name back.

"There's been a concerted effort to steal Christmas," Falwell told Fox Television.

The Nova Scotia logger who cut down the 48-foot (14-meter) tree was indignant and said he would not have donated the tree if he had known of the name change.

"I'd have cut it down and put it through the chipper," Donnie Hatt told a Canadian newspaper. "If they decide it should be a holiday tree, I'll tell them to send it back. If it was a holiday tree, you might as well put it up at Easter."

Falwell and the conservative Liberty Counsel led a campaign that threatened to sue anyone who spreads what they see as misinformation about Christmas celebrations in public spaces.

The controversy reflects the legal vulnerability of city and state governments over taxpayer-funded displays of religious icons and concern over crossing the line in the separation between church and state.

Last year, California Gov. Arnold Schwarzenegger lit what he called a "Christmas tree" at a state ceremony. The year before, he and former California Gov. Gray Davis presided over ceremonies for the more secular "holiday trees."

In Boston, many residents voiced their dismay over the Web site that promotes a December 1 ceremony for "Boston's Official Holiday Tree Lighting."

Christmas has become too politically correct, said 64 percent of people who responded to an online poll by a CBS television affiliate in Boston.

Boston Mayor Thomas Menino said he would keep calling the Nova Scotia spruce a "Christmas tree" regardless of what it said on the city's official Web site.

"I grew up with a Christmas tree, I'm going to stay with a Christmas tree," Menino told reporters on Thursday.

But the controversy cast a pall over a long-standing tradition between Boston and Canada. Nova Scotia donates a tree each year to Boston in gratitude for the city's help after an explosion killed about 1,900 people and injured 4,000 others in Halifax in 1917.
