I celebrate the Solstices, and I take off from work for them too. Gee, and I guess I was wrong when it seemed all my Jewish friends were excited to be celebrating Hanukkah. All that prep time and tradition they put into it - made it seem like a big deal to me.
While "majority rules" is the basic premise in the United States, it does not cover religion, thank goodness. Of course Christmas is just the way Christians tried to win over the Pagans way back when...I have no problem if someone says "Merry Christmas" to me, as I'll take all the good, cheerful feelings sent my way, and I hope they don't mind when I respond "Blessed Yule".
Do you get Solstice off? My company makes me take Christmas off, but Solstice I have to take off if I want it. And yeah, a lot of Jews enjoy celebrating Hanukkah, but it was a minor holiday in the Jewish calendar that has - in some ways - been promoted by American Jews to provide Jews with something like parity.
If Pagans and Wiccans were the majority, we'd get Solstices off and when people call Halloween a Harvest Festival we'd say "you are trying to take the Goddess out of the Seasons!" (Which DOES seem to be a driving factor behind Harvest Festivals - I think Season's Greetings and Happy Holidays is less about removing Christ from Christmas and more about having an inclusive greeting that will cover the half a dozen holidays and celebrations that happen between Thanksgiving and the Superbowl - you can leave your Happy Holidays banners up in the mall until the first week of January - the Merry Christmas ones are dated on the 26th
(Disclaimer - as a Unitarian I've been known to celebrate Christmas as a religious holiday. Halloween as a religious holiday. Solstice as a religious holiday. And even Hannukah. I don't make a habit of fasting through Ramadan though. We like our holidays - and since we come from a variety of religious traditions, we claim many of them.)
Halloween and Christmas are secular holidays - celebrated by some Americans as religious holidays. You can't read too much into a secular corporation choosing to market to either of these holidays.
