Indeed, but I wonder how they deal with passages like Revelation 14:11, Matthew 25:41, or Mark 9:43.

Frequently, by not knowing about them.

Its conceptually possible to believe that the Bible is full of nonsense yet Jesus really did die for our sins. But nobody ever seems to actually hold this position. Or if they do, they never seem to come out and say it.

They do, but they express it as either "the Bible was written by fallible men" or "it's all Deep Metaphor".
