Refusal

It's been awhile since I have academically interacted with atheists, so this recent activity has been interesting. One thing that atheists repeatedly miss and misunderstand is that of categories.  Whenever the subject of God comes up, the atheist always demands some sort of proof, something empirically verifiable.  But as I point out, over and over again, they are confusing categories.  You don't ask what blue sounds like, you don't ask about the texture of yellow, you don't mine diamonds with qtips.  In the same way, you don't understand the things of God by scientific study.
And a recent revelation has moved me to the point of not even engaging atheists any longer.  One atheist actually said, you Christians can offer no proof.  Even if you managed to show something, we wouldn't believe because it might be a hallucination.
In other words, atheists refuse to believe.
