Reasons NOT to celebrate Christmas

1. Because of the many pagan origins. "Jesus" was never "the reason for the season" and there is NO scriptural connection between the December 25th Christ-mass and the Hebrew Messiah, the BRANCH of David. There is much better evidence that Yehoshua was born during the Chag of Sukkot (Tabernacles), not during a Winter Solstice. See the study: Biblical Dates for Messiah's Conception and Birth.
2. Because all of its modern religious validity is rooted in Roman Catholicism. If you're a Roman Catholic, maybe you should celebrate the "mass of Christ". If you're a Christian who only prescribes to Biblical Judeo-Christian principles, then maybe you should rethink WHY you're so wrapped up in this not-so-holyday. Why are you unwittingly submitting to the masters at the Vatican? Many Christians have historically refused to celebrate Christmas precisely because they only wanted to submit to Messiah.
3. Because Christmas is harmful to Children! See this great study on the subject.
4. Because Christmas is harmful to your wallet! You'll have more resources for other more noble giving.
5. Because it is primarily driven by secular-humanist greed which has flourished within the bounds of the West's mutant form of capitalism now subjugated to the tyranny of corporatism and SPEND-SPEND-SPEND consumerism... which has greatly contributed to the economic indebtedness and enslavement of Christian nations in the West.
6. Because the Zeitgeist and similar movements discredit Christ on the basis that "Jesus" was simply re-fabricated out of older bizarrely similar deities (and thus "Jesus" probably didn't even exist). Regardless of chicken-or-egg arguments where "who came first" issues are discussed... the reality is that the Hebrew Messiah looked very different than the modern Catholic-pagan version... which appears to have hijacked the worship of Attis, Osiris, Horus, and Mithras (and related Christmas-like winter-solstice worship festivals). Why did Rome need to make Yehoshua look pagan and non-Hebrew? Why do you need to look like a pagan?
