There shouldn't be any controversy, but there is because the OP wanted there to be. The idea and purpose isn't to have a specifically Christmas festival or Ramadan or whatever, it's the idea of just having a fun event to enjoy in game. Christmas IS more commercialized so of course that makes sense, but who says it has to be called Christmas, this one isn't called Halloween. Celebrate a wi yet festival with snow, decorations, gifts, Santa or whatever. Enjoy the event in the spirit it's intended, something fun to enjoy and a little something different in the game, not so much some stupid controversy for no reason.
