At a time when Americans of many faiths – and even no faith – gear up to celebrate Christmas this year, a first-grade teacher in Sacramento Co., Calif., says she's been ordered by her principal not to utter the word "Christmas" at school. The 24-year education veteran, who wishes to keep her name and the school anonymous at this time, claims she and two fellow instructors were told that use of the word "Christmas" in the classroom or in written materials was now prohibited.
