I think you'll find the true Christian attitude these days (not the attitude of hard-right American Churches that get rich selling tickets to heaven (acknowledgements to Mark Knopfler)) is, if you want to celebrate Hanukkah, go ahead. If you want to participate in Saturnalia, then pray do so.
If you want to celebrate Kwanzaa, then, how can we object ... some of our number might even join in! (Thank-you for, at last, finding a truly secular festivity to compare and contrast with Christmas.)
But what annoys Christians (so far as I can tell) is that atheists have not been celebrating a purely secular festival such as Kwanzaa, or even non-Christian festivities like Saturnalia, Samhain, or the Making of Pasta Dough Day, but Christmas instead. They refer to it as Christmas, they acknowledge it is a religious festival, they give religious icons, such as Christmas cards with holy scenes and biblical quotations to each other. They may even participate in religious ceremonies.
But a few of the more sour ones say, Look here. Celebrating Christmas is an infringement of my rights. I demand it be called Winterval to save my sensibilities from being offended. And drumming up an excuse that a few tax-payers' dollars are being spent to make everyone's life a little bit more cheerful strikes me as petty and mean.
Moving on: A recent court decision in England has held that it is unlawful to hold Prayers as the first part of local councils' proceedings http://www.bbc.co.uk/news/uk-england-devon-16980025 . The case was brought by an an atheist organisation after a member of that council complained because he felt his rights were being trampled upon by forcing him to participate in something he objected to.
Any comments?
