Judging by the responses that seems to have totally ignored the definitions I put forward.... people are still under the impression it is binary what you believe in. You either believe their is, or their is not.
What about those that are just not convinced but if science could prove some prime mover (god, aliens, a large ball of spag etc) caused the universe then they would out of natural curiosity want to investigate it and may adopt that approach? What about the apathists (yes I coined that word), the group of people that just don't give a fuck?
It is not binary. Atheist is just not convinced, the onus if on anybody else with any idea to convince them of that idea. Brand us what you like, just don't try to debate with us any "logic" at the same time. The OP here has failed at the very title of this thread. Had he have said 'Anti-theist' instead of 'Atheist' it may have had some sort of meaning.... to somebody that also had limited oxygen in the womb.
All it really says is 'A person that is not convinced does not exist' ... errr ... wtf?
