As a non-Christian in the West, December is the most obvious reminder that you are not the typical Westerner. The bogus "War on Christmas" notwithstanding, it's frustrating to have otherwise liberal Westerners tell Jews, Muslims, and other non-Christians that Christmas is "secular."
No. It's not. Please stop saying that. It's insulting to those of us who are reminded, every year, that we are "others," to be told that YOUR holiday is secular and for everyone.
Please understand, I'm not saying that you can't enjoy the holiday. Hell, I will gladly take a day off. But until you start celebrating Chanukkah with me, I'm not buying that Christmas is a secular holiday. I mean, for goodness' sake, the name is literally "Christ's Mass." Just because you as a people chose to forsake the religious aspects in terms of traditions doesn't mean that the holiday loses its intrinsic nature as a Christian holiday.
I'm not saying this because I want you to stop enjoying your holiday. I just am sick and tired of people on this site and others trying to convince me and the rest of the non-Christian population in the West that Christmas has magically become a non-Christian holiday.
(I will possibly accept the Japanese exception, but their appropriation of the holiday is unusual and requires a different discussion. My argument applies to the West, which remains predominantly Christian in terms of background.)
Please, save your non-Christian friends an eyeroll, and stop trying to tell us that Christmas is our holiday too. It's not. And that's okay. We have our own holidays that we enjoy, and we will continue to enjoy your calendar holidays anyway. ;-)
Merry Christmas! ;-P
