This is something which I've been wondering about for a while.
Is it because people on the left have the same frequency of spirituality, but Christianity is deemed right-wing?
A poll I can't find right now, had a breakdown of US voting patterns and religious beliefs. People who voted republican were more likely to believe in God, whereas democrat were more likely to buy astrology, tea leaves, and that sort of nonsense.
A roommate of mine told me she went out a few nights ago with some of her friends, yada yada yada, they discussed astrology, about half of them believed in it. Why? I couldn't believe people who get into graduate school could believe in such tripe even if it's the humanities. Half the table? Come on!
Admittedly, I should not be using different language for christianity and wiccanism for example. But they are differemt. People are taught Christianity from a young age, whereas with Wiccanism you have people decide to seek it out, they don't have the irrationality in their life and so they go looking for it. That's infinitely worse.
