It isn't a case of Tantrums. And Christmas is not just a "conservative" holiday. It is however the only holiday celebrated in the United States and many other countries in the world that Progressive leaning media goes to great lengths not to mention by name, going so far as to censor the usage of it and/or change existing media to remove references to the holiday. a major case in point about that is the Cheerios Christmas Carol commercial which has been edited in recent years to completely remove the word Christmas from being mentioned at any point during the commercial despite the fact that the story being portrayed in the Cheerios commercial is "A CHRISTMAS Carol".
So frankly I think people have every right to be annoyed or angry about the overbearing censorship on Christmas, since it is again the only holiday in the United States celebrated by a major majority of the people while simultaneously being stricken from public mention with the insinuation that it is an offencive and it non inclusive holiday.
