And why you shouldn't be one, either.
Do you believe in ghosts? Do you think its possible that there could be one in the room with you now, invisible, watching. Not that there is, mind you. Just that the possibility exists for you that there could be a ghost in the room? If so, you are not alone. Many otherwise reasonable folks believe such things, and more.
Most people, when asked, also profess faith in a god or religion. Many attend church services. They are theists. They are otherwise reasonable people. They raise their families. They balance their checkbooks. “They” are almost everybody here in the USA. They believe. And they want everybody else to believe, too, in something, anything really, as long as you have “faith.” Not having faith is considered to be a character defect. To believers, if you don’t believe, you are an atheist. This is, of course, a false choice fallacy.
To this non-believer, theism is superstition. Faith in a god, or faith in superstition of any kind, is nonsensical and I see no reason to take a position for or against any nonsense. Because of this belief of mine, I don’t call myself an atheist. I don’t feel the need to be against theism, any more than I feel the need to be against astrology or alchemy or the Flying Spaghetti Monster. Why would anybody take a position for or against something that clearly doesn’t exist? I can’t imagine. So, for me there are no ghosts. Faith is just a word. And I am certainly not an atheist.
I’m simply not superstitious. Boo. Ha, gotcha.
