Agnostics

Yes, benny, there is. That is a stupid question, care to either define what you mean by special or better phrase that question?

Also, see my updated previous comment please.

Okay.  Why is it that my beagle, a thinking agent, is not atheist, but a person, a thinking agent, is an atheist by default?

Because your beagle won't ever evolve a mind capable of understanding and reacting to theism, whereas a baby will. Like I just said, atheism is merely a convenience. We call atheists those thinking minds that either will one day or already do understand theism, but are not theists. Most of language works like that, it is an utility. Don't search for deeper meanings where there aren't any to be had.
