The cutesy little commercials and signs and even storefronts (guess where I won't be shopping) that say, "Remember, Jesus is the reason for the season" irritate me to no end.
Don't you remember anything from grade school science? The tilt of the earth's axis is the reason for the season.
Christians don't get to monopolize an entire season. They don't even get to claim the entire month of December. There's Hanukkah, Kwanzaa, Yule, Bodhi Day, and in Islam there's either Eid ul-Fitr or Al-Hijra depending on their calendar.
Jesus is not the reason for the season. He's the reason for your holiday of Christmas, for which you stole the practices and traditions of Pagans. Get over yourselves.
