At this point, there are just too many contradictions, I'd rather forget and simply accept the absurd.
For example, being an atheist, I don't particularly believe in holidays myself. I do enjoy myself with my family even if it mean a few capitalists make a little more money during the season. On the whole, a meaningless event makes the whole world happy.
I'm of a fairly open religion (Hinduism). So, there aren't ardent rules you need to waste time with.
