Hard disagree, no one uses the term "Chirstmas" anymore. We have Ramadan, we have Divali but just "Holidays" instead of Christmas. You won't find any major brand or TV station using the term Christmas.
i don't know where you get your information from, but more people still use the term "Christmas" than people who even know about some of the other Holidays.
Oak inside. Dark and soaked muddy leaves outside. Jumping under the gelid rains hammer. Yup, we have a very nice weather today in resume. Light gray and yellow.
