The list author says: "I personally LOVE the Christmas holiday; but think that one should get "both sides." There may or may not be a "War on Christmas," but there ARE Christians who oppose Christmas; e.g., Scottish Presbyterians; Jehovah’s Witnesses; the Philadelphia/United/Restored Church of God; the Church of God (Seventh Day); some 7th-Day Adventists, etc.
While their arguments may not persuade you (they haven't me!), there are some valid criticisms of Christmas (e.g., commercialism; some aspects of Santa) that we can all acknowledge.
