> You mean they have a confession? That is not the same thing as being religious. I for example have been born into a confession and till I went through the not uncomplicated act of leaving church I would have been counted as religious. I have been an atheist since I was 12 or so.
I think there are four different groups of people:
(1) people who say they believe in some organised religion and it is a big part of their lives
(2) people who say they believe in some organised religion but it isn't a big part of their lives
(3) people who say they don't believe in any organised religion, but nonetheless report having some "supernatural" beliefs (ghosts, reincarnation, etc)
(4) people who say they don't believe in any organised religion, and furthermore report having no "supernatural" beliefs (naturalism, physicalism, materialism, atheism, anti-supernaturalism, etc)
The problem with labels like "religious" or "non-religious", is it is unclear which of the four each label encompasses. Some people define "religious" narrowly to only include group (1), others also include group (2), some will even include group (3).
Not all "atheists" belong to group (4). I know a person who calls themselves an "atheist", and they literally meet the definition; but they also believe in ghosts and an afterlife – which puts them in group (3) rather than group (4). They actually told me once that when theists die, they will be shocked to find out that there is no God, and they "wasted their lives" worshipping an imaginary being. Those kind of beliefs are probably much more common among the general population than among the kind of people who frequent this site.
