This is at the top of felch grogan's profile page here on Atheist Nexus. It makes me laugh, even though I don't believe in luck.
As an ex-Neo-Pagan, it blows my mind how many people who fall under the Neo-Pagan umbrella (Neo-Druids, Wiccans, Heathens, Asatru, etc...) come from one religion with an entire set of superstitions, only to become Neo-Pagan and exchange them for an entirely new set of superstitions, or even to add them to the superstitions they already have.
Unfortunately, I was one of those people. One of these days I'll post about how I went from being a baby, newly born with no indoctrination; to my years of self-delusion; finally to atheism. I literally studied astrology (among other things) for 20+ years. I feel like I have a lot of catching up to do educating myself in useful studies.
I knew someone once who had to throw the I-Ching before they made any decision. I wonder if they ended up with carpal tunnel syndrome. Then there are people who make offerings to the "fey", and I'm thinking... I'll bet that would be put to better use at a soup kitchen.
That's just the tip of the iceberg.
Any stuporstitions that you used to believe, but have thrown off?
