I don't mind Christmas per se. Indeed, as far as I'm concerned it represents an excellent opportunity to get Chinese food, go see a movie, or hit the ski slopes while seeing virtually no crowds. But a surprisingly big stresser this year is how to respond when someone wishes me "Merry Christmas".
Of course, when unprompted my seasonal well-wish is "Happy Holidays". I've even thought of what I'll say if someone chides me for not saying "Merry Christmas": Ask them why they hate Protestants (What do you think "Christ's Mass" means?). But in many settings, someone will tell me -- with good intentions always -- "Merry Christmas"! And what do I do then?
Stephen Feldman, of course, would tell me that I should reply with a plea: "Please don't wish me a Merry Christmas!" But that seems quite churlish, and cuts against my adopted-Minnesotan instincts. Option two, which is what I tell myself I should do but never can bring myself to pull off, is to shoot back with a bright "Happy Channukah" -- matching sect for sect. But what can I say? I'm a very non-confrontational person. So generally, I just say "thanks -- you too."
But the whole ordeal annoys me. So I'm going to echo Feldman's plea. Happy holidays is the way to go. Jews are already making a concession in pretending that this is the holiday season, when of course the whole reason a podunk holiday like Chanukkah gets elevated to prime status is because this time of year is actually spectacularly unimportant to traditional Jewish ritual and practice (a point which was made by Justice Brennan in Allegheny County v. ACLU, 492 U.S. 573, 646 (1989) (Brennan, J., concurring and dissenting), and has since been ignored by every other person on earth). The least y'all could do is not shove it our faces, or the faces of the various other religious denominations that don't frankly care that Christians like celebrating the birthday of Christ months after it actually happened.
UPDATE: Phoebe Maltz independently explores why (some) Jews dislike Christmas. I think the self-deprivation angle is pretty spot on -- there's an ascetic's pride in separating yourself from the Christian majority specifically by denying yourself what by all accounts is the best day of the year for
UPDATE #2: Another contribution, courtesy of Howard Wasserman, examines what Christmas specials Jewish children are allowed to watch. I actually don't know if I saw any of these.
