In discussions with atheists, if they hadnt already told me that they were atheists, the arguments etc were no different from satanism arguments.
Is atheism, satanism?
Are atheists unwilling satanists?
Is this why atheistic satanism is so common?
No to all of the above, pretty obvious right? People lack a belief in a deity for any number of reasons, but I'd hardly say the common link is an interest in or devotion to satan right? So by definition not a Satanist correct?
Your questions did trigger something in me that I've always wondered about though. How many
Christians are atheists? I don't just mean the church leaders, who might go here
The Clergy Project - Religious Leaders Beyond Belief but the people who fill the pews every Sunday. When I was a Christian I went to a
lot of different churches, some traditional, but mostly evangelical happy clappy ones, the "bible believing" variety. I was quite surprised (maybe a tad naïve in those days) to find a lot of disbelief and apathy in the faithful, it was clearly a case of tired tradition for some, a "social" thing for others, a lifestyle hobby for a great many. I seriously doubted they
really believed back then when I
did believe, not just the usual religious judgemental attitude towards any other believer that has a different theology/doctrine to your own, you could just tell their heart wasn't in it. Lets be honest it is something that is fairly easy to read in other human beings about anything, not just religion.
I wish being an atheist made your hair turn green when you step into a church. I'd have a lot of fun watching all the green haired people coming out after the service, trying to cover their embarrassment with their hats!
