I personally think the whole thing is stupid.
Christmas isn't even near Christ's alleged birthday. The historical facts regarding his birth all point to a much warmer month. Most likely somewhere around June or July. You're 6 months late! Second, the date of Christmas is shamefully stolen from the Pagans who had numerous winter holidays around the 25th. Third, Christians even BANNED the holiday numerous times throughout history both in the New and Old worlds because people were using the holiday as nothing more then a day to party and get extremely plastered. Fourth, the vast majority of rituals from presents to trees to mistletoe are all pagan. Fifth, Christmas today is effectively nothing more then a commercial holiday meant to ensure that retailers go from red to black on their fiscal year. Six, the fact that numerous non-Christians celebrate it as a day for togetherness devoid of religion shows it has effectively become a secular holiday.
Atheists need to get the facts straight and move on. This is stupid. It's a commercial holiday that was stolen from the Pagans and celebrated in many pagan ways. Sheesh.
