What you provided aligns perfectly with what I've said. You don't get to define atheism so that it makes it easier for you to argue against. That's just petty.

If the people that identify with and label themselves atheists have made an effort to have a more nuanced definition published that does nothing to strengthen an argument against it.

Do you know how the English language works? If people start using a word the way that it is used is what the word becomes in a dictionary. Dictionaries respond to popular usage of words not the other way around. Language evolves get over it. You are just distracting with semantics at this point.

Let's forget about the word and focus on the concepts. An agnostic lack of a belief in gods is seemingly the only reasonable stance to take.
