Since I’m (modern-day) 1/2 pagan, 1/2 atheist, and 100% skeptic, even in my own spiritual/academic beliefs [well, unless it concerns trees (I hate chain saws.), nature, and animals–always a supporter of their rights, and souls!], I’d thought I share some links re: the pagan origins of Xmas.
Here’s a interesting site re: paganish Yule celebrations and symbolism: http://wicca.com/celtic/akasha/yule.htm
Other links re: Xmas origins.
