Because of the holidays, many people are fighting over religions and beleifs, so some ground rules need to be put into place.
Please, do not go around with all this personal evidence that Jesus was alive or that he was the son of god or whatever. You can talk about it, but don't get all angry when someone thinks Jesus doesn't exist or they don't believe in the same God as you do. News flash: there's a bunch of different religions and most people probably don't believe in the same God as you do.
Even if you don't believe in Santa Clause, please don't ruin the fun for many others who do. It's not very fun when someone ruins a thing that you cherish, especially the day before.
Many other people have different holiday traditions. For instance, Jewish people who celebrate Chanukah light candles every night. And, some Spanish traditions include decorating a log, and singing a song to get presents. Whatever you do, respect others
Lets keep everyone in the holiday cheer by not yelling at people when they talk about the holidays they're celebrating. It really brings down the mood
