Most religion is faith-based, rather than logic-based.

[Pope George Ringo II]

57. Great. You've finally found one old dictionary which agrees with you.

Your first cite was dishonest. Nothing more, nothing less.

Your second cite says you're wrong. Bloody brilliant, that.

And your third is generally regarded as an obsolete error from the time people like you had a say in what the word meant. You don't anymore.

So, no, you still have nothing but a lie about somebody else's position.

Serious question: Can you document even one atheist here who actually agrees with your erring definition of atheism?

Followup question: Has it never occurred to you at any point that this glaring omission might mean you're just pissing people off by slandering their position, and preferring to argue instead with a lie you've invented?

Bonus question: Is there any answer to that second question which reflects well on you?
