How is posting a dictionary entry and then drawing logical conclusions from it trickery ?
It’s a fraud because it’s a clumsy and misleading definition, not appropriate as a basis for a philosophical discussion. My Webster’s just defines an Atheist as “One who denies the existence of God”. The first online source that I went to defines Athiesm as Disbelief in or denial of the existence of God or gods . Neither requires the acknowledgment of the existence of something in order to disbelieve in its existence. That’s silly.
Come to think of it, if you have to so misrepresent atheism to feel confident in your religion, it looks like your faith is dependent on my ideology, not the other way around.
