Possibly, but it is a very contrived example. It is for just this reason that people make up labels like "apatheist" and "agnostic"--to try to classify borderline cases. If Huxley had considered the definition promoted by folks here to be reasonable, he never would have rejected the label "atheist" and coined the word "agnostic". What I think is really going on with "atheist" is that it carries a great amount of social stigma. So some people don't want to use it to describe themselves. Others strive to keep the label but give it a broader definition than it has had in the past. The new definition then becomes a tool to try to drive change. After all, if babies are atheists, how can everyone stay mad at them? Sure, they whine a lot, and they sometimes make a mess, but aren't they also cuddly and cute?
So, what's the conclusion? If babies aren't necessarily atheists and Johhny (possibly) is, then neither "lack of belief" nor "rejection of belief" fits...
