I disagree. I think it should be Political Correctness Gone Challenged Mentally.

Banning Christmas in public places is probably what you mean. If it's ONLY Christmas that's being displayed, then there's a problem with that because it's more than likely that it's people who have non-Christmas winter celebrations that don't feel acknowledged. And since you aren't an atheist, you're very likely wrong on how they feel abut celebrations.

As an atheist who grew up devoutly Christian, it doesn't bother me that other people celebrate Christmas with public affirmations of their faith. It doesn't even bother me when they play up the religious imagery of Christmas or other such holidays. What I don't like about (some) Christmas talk is that ordinary Christians who talk to me about it usually assume that I buy into the same worldview that they do, that my views on Christmas things are the same as theirs because the way they think is natural and correct. Without acknowledging the possibility that Christmas might mean something else to me, they imply that my view is something "other" or "deviant," and I don't like that.

Having said that, I'm not sure what you mean by "banning" Christmas. If you're referring to incidents where the word is replaced with Holiday or some other euphemism, I take issue with your definition of banning. It's simple courtesy to say that, as while not everyone celebrates Christmas as such, the idea of a holiday season occurring around that same time with shared customs that transcend religion is much more universal. It's an inclusive term that reduces the potential for alienation because of unwarranted assumptions about the other person's beliefs. It's not perfect, but it's unquestionably well-intentioned.

Also, one minor thing; Your phrasing (the idea... shouldn't bother you) misses the point somewhat about tolerance and Political Correctness in general IMO. It's not about whether one person is right about subjective things, it's about you accepting that they're allowed to feel that way, and then accommodating them as far as is reasonable. You don't get to decide what it's acceptable to be offended by, you just get to choose whether you will respect the wishes of those who claim offense, or whether you won't.

Hope this clarified things, and without being patronizing or otherwise douchey (I sometimes come off that way even though I mean nothing like it).

There are varying levels of it written into government policy at least in government workplaces. The tolerance policies technically prohibit me from wishing a fellow Christian a merry christmas (in fact, they prohibit dialog that would allow me to determine I'm speaking to a fellow christian in the first place.) Its often ignored though.

And I agree some of it is sensitivity. Government has a way of pushing further and further with a program or policy so when we see a municipality take down a nativity display, it sets us on guard. What we have to remember is that the very presence of that nativity scene was probably putting the rest of you on guard to begin with.

Oddly, we are allowed to put up religious iconography in our own cubicles as long as nobody complains (I have a construction paper cross that was given to me by a coworker's daughter.) I think that's why we usually ignore the speech policy (its weird and I hear conflicting reports.)

As a student rabbi, I have absolutely no problem with most Christmas decorations, carols, or Santa. I'd prefer it if carols that mention Jesus and Nativity scenes stay out of public schools and public buildings, but deck as many halls with boughs of holly as you want. And I hope my Christmas will be merry, just as I hope everyone has a "Happy Hanukkah", whether or not they actually celebrate the holiday. Which is why I respond that way whenever I receive a "Merry Christmas," and I hope no one is offended by that.

With regards to your cubicle, I don't think that is odd at all. After all, that's your space, and you should be free to decorate it with anything that is not actually offensive/hurtful to others. I think it's a bit like how you can put up whatever Christmas display you like on your lawn even though the public can see it.
