Are you a believer? Do you think it is enough to just say "I do not believe anymore for the next 2 weeks", really meaning it? If so, it means that the faith was not very strong.

Except for some specific cases, one usually grows with a religion or non-religion and this deeply forges one's perspective.

I'm an adult convert. So what I'm telling you is, I didn't have to start out believing; just curious. Obviously atheism is different because there is no particular doctrine or liturgy to involve yourself in, but you could certainly read atheist polemic.
