To me, the implication is that the individual *knows* there are no gods, begging the question "how do you know?"
But unless you are the person, it is irrelevant what implications you hold.
I may not have chosen the best wording. I suppose using the word "honest" or "dishonest" does inevitably mean that one is knowingly being untruthful if they take a particular stance. Perhaps I should have phrased it differently and asked if atheism is intellectually flawed, or perhaps unsound, if one professes to "know" that there are no gods.
Then it's a good thing most atheists are smart enough to just believe there are no gods.
Anyone so limited that they can only spell a word one way is severely handicapped!
