I have a neighbor who loves these celebrations. She doesn't care much about religion or what the background is of a holiday. She'll do just about anything for fun. I asked her if she'd go to a party to celebrate Hitler's birthday, she at least said no. But as long as she finds something cute in a holiday, not her own religion, it doesn't matter to her, she's happy. I am saying this because it sounds like something you are saying.
I like to put the FUN in fundamental.
