That atheism is not rationally justified

[Dolorian]

1. it's one big red herring: it doesn't matter whether the position is rationally justifiable or not, it only matters that people don't buy what the theists are selling.

But is you not buying what the theists are selling a rationally justifiable decision?

2. At the end of the day, it's nothing more than a surreptitious attempt to shift the burden of proof: "I don't have to provide justification for God, you have to justify why you don't automatically accept what I say!".

That is one way I feel about it too. It is also trying to set both positions on equal footing without rational justification.
