Back in 2010, the fellow portrayed here, Ken Pulliam, made a fascinating point.
Pulliam was the proprietor of a blog with the autobiographical title, "Why I De-Converted from Evangelical Christianity." Presumably he stopped adding new posts when he came to believe that he had said all he needed to say about that de-conversion.
One of the posts of this blog in particular intrigues me. It is dated June 18th of that year. I'll provide a summary in a second but if you'd like to read the whole thing, here's a link:
Pulliam ceased to believe in the existence of the God of evangelical Christianity because he came to believe that the God depicted by that tradition would be a highly unethical being, if He existed. And that inference takes most of the point out of postulating His existence.
In order to reach such a conclusion, one needs an Archimedean "place to stand," a meta-ethics that allows for ethical judgments that encompass both a created world and its postulated creator.
Pulliam invokes intuitionism, specifically as expounded by Michael Huemer in a 2005 book, as that Archimedean point.
Here's the amazon page on the Huemer book:
