In order to understand the difference between black and white magic, we have to assume magic exists. I assume magic exists, though I would point out that just like gravity and evolution, magic exists whether we believe in it or not.
I am not a fan of Christmas. Admittedly, there are a few good things about it: the pretty lights, a general spirit of giving, and peppermint lattes. As for the rest of it, I could just soon as do without, especially the one thing that makes Christmas, well, Christmas. That one thing is not holiday cheer, nor is it a sense of peace on Earth and good will towards mankind. It’s certainly not the birth of Christ, though that factors into things.
What Christmas means to me can be summed up in one word: GUILT.
