I get this one a lot, especially living in the Bible Belt of the United States. A lot of Christians get terribly upset that Santa is more popular than Jesus' birthday, and a lot of them don't like the term "Happy Holidays". It shouldn't really be something to be mad about it, even Christians celebrate New Years which I'm sure is part of those happy holidays. And second saying "happy holidays' shows you're considerate to those who may be Jewish and celebrate Hanukkah instead. I always believed being considerate was a moral virtue, and being arrogant about your religion was not a thing to be proud of.
