Terry: "Being without belief or without god is the "a" in a-theism. A means "without". Theos=God."
Clearly you haven't read the entire thread.
No, there is no reference to "belief" in 'Athiest'. That is false.
It means "No God", or "Without God". It's original meaning was "denial of the Gods". It does not refer to a lack of belief in God, but to a belief in the nonexistence of God or Gods. "Denial" of their existence. An atheist is not agnostic, he has taken a stance against the concept of God and against those who believe in God.
Babies take no stance, they have no belief. Agnostics take no stance, they have no belief. Atheists take a stance - against theism. Therefore babies are not "atheists". You are a zealot Terry. Babies don't share your zeal in attacking Theism. Stop trying to co-opt newborns into your religion! LOL.
Had you been born an atheist you probably would never have adopted Christianity. But it was your lack of any opinion on the matter that allowed a new belief to be 'installed'.
What you call the "misidentification" of atheists is it's original and it's primary meaning. For evidence of this, read the thread.
