You're most certainly welcome! I'm an odd one. I'm a theist. I'm a Bible believer. The Bible refers to many gods. Some were mere mortals not unlike ourselves. Some were supernatural. A person or a thing has to become a god by being venerated which is to say, to be attributed a might that is greater than the one attributing it. So I believe in several gods mentioned in the Bible. Veneration isn't worship. So, the Bible mentions a man, a King of Sumeria whose name was Tammuz, as a god. I believe this man existed, as a god, but not my god. So! do I believe in a single god? I believe in many gods, some who have existed, some who haven't. Some who were supernatural some who weren't. One, Jehovah, which I place above, that is, foremost, over all others.
Very good question, and surprising survey results, if they are accurate they certainly are surprising to me as that hasn't been my experience, either as an atheist for the first 27 years of my life, and having 99% of the friends and family I've known all my life that are atheists, or over two decades discussing the subject with atheists online. I think that the reason for this is that the atheists we tend to encounter on forums like this are, more what I call, militant, meaning more outspoken and aggressive. I think they tend to be more narrow in their approach. Then again, Buddhist, Confucians, Shintoists, and Taoists would be atheists that we would likely encounter who weren't "Atheists" as such, but atheists never the less. And there's the rub, you see?
Really all religiosity is, is a specific system of beliefs or principles strictly adhered to. For example, I watch South Park religiously.
So, there's all this debate about 1. Whether gods are supernatural or not, whether or not a god has to even exist to be a god and therefore do gods exist, and does one have to worship a god in order to believe in it? and 2. Does a religion need gods, does a religion need rituals, etc. or are those religions without gods, rituals etc. really only philosophies and, apparently from the militant atheists perspective especially, are commonalities other than a lack of belief necessary?
