Nice try AS (fool, swine), but you know that's not the context of the word "fool" which refers to those who say there is no God.
The Hebrew word is nabal, which often refers to an impious person who has no perception of ethical or religious truth. The meaning of the text is not “unintelligent people do not believe in God.” Rather, the meaning of the text is “sinful people do not believe in God.” In other words, it is a wicked thing to deny God,

They'll be plenty of smart folks in hell. Do I need to explain "swine" to you again as well?

It is irrelevant what you think. What matters is the TRUTH.
