"Christmas is an annual festival, commemorating the birth of Jesus Christ, observed primarily on December 25 as a religious and cultural celebration among billions of people around the world." https://en.wikipedia.org/wiki/Christmas
This may be a disturbing thought to some, but a great many people don't give a damn about any supposed virgin birth. To them, it's about getting time off from work to visit family, various pagan-derived decorations around the home (https://en.wikipedia.org/wiki/Yule), seasonal desserts, and of course consumerism/consumption (particularly the giving of gifts, which is what "like Christmas" in this instance refers to.)
