my grip about this study is it seems to confuse the term atheist with non-religious. just because you haven't aligned yourself with one of the other relgions of the world does not make you an atheist.
an atheist believes that there is no god.
a non-religious (in the way they are using it here) means you aren't associated with any church/whatever.
as far as i'm concerned, atheisism is a religion. if you haven't given serious thought to your choice to not believe in god you are more agnostic then athiest imo.
Hmmm I see your line of thinking but I don't agree entirely. While some atheists are obsessed with religion, some just flat out think there is no god and that's it, they don't think anything else and don't persist with it.
analogy time. xD
a "white" child grows up in a community of mixed heritages. this child interactes with, becomes friends with, and generally ejoys the company of other children of various racial backgrounds. this child could be classified as "not racist".
another "white" child grows up in an all white community with all white family, friends, and neighboors. thus, due to ignorance of the existence of other racial backgounds, habors no feeling of hatred or discomport towards other racial backgrounds. does this mean the child can be classified as "not racist"?
imo, no. if the second child was placed in a room with a black child the white child could either be comfortable or uncomfortable. without the challenge no outcome can really be decided upon.
some athiests will be more committed then others in the same way that some christians will be more committed then others. my objection is many of the so-called athiest i've met are actually people who's parents never took them to any sort of a religious institution in any form and literally never gave any such concept any thought. that does not challenge their mind and does not mean they are really athiests. most of the "i found religion late" stories i've ever heard generally start as "I was exposed to religion for the first time when ...".
