Sigh... we are all just liars/in denial

[Welsh cake]

The Bible says the fool says in his heart, 'There is no God'. It's nasty, but it's clear acknowledgment of our existence

Its not nasty, its laughably absurd because the quote from Psalms asserts we are abominable and cannot do good. That is wrong.

and implies that people who really think there is no God are pretending to.

No, it asserts we are "ignorant" of the demonstrable truth that is God. Which is also absurd because the Biblical God is not self-evident otherwise there wouldn't be any debate, there would be no atheists.

Besides if you use the Bible's own scriptures against them, every theist who throws that quote around is going to Hell for calling us "fools". >.>

You can't argue with someone who claims to know your mind better than you do and accuses you of lying if you try to explain that they have the wrong idea.
