Everyone old enough to read the whole text comes to it with a worldview - and they read it in a way that makes the most sense for them.
There has never been an unbiased reader of the Bible.
There’s a difference between reading the Bible with a worldview and reading the Bible to CONFIRM your worldview.
Think of it like a menu, you can read a restaurant menu to see what they have, now you’ll naturally pay more attention to the foods you like than the ones you don’t (your worldview) but you’re reading the menu. Or you can read a restaurant menu to see if they have western BBQ burgers, it’s still your worldview but now instead of reading the whole thing you’re skipping large sections that wouldn’t have the burger, no reason to check out the appetizers, salads or fish section when all you care about is the western BBQ burger, you might even miss the fact that you’re in a Mexican restaurant.
Camping is in the later category. He’s all about Judgment Day, that’s all he’s reading the Bible for, he wants to figure out the end of the world. He’s convinced the clues are in there somewhere, this isn’t the first time he’s predicted it, and if he lives long enough it won’t be the last. And he quite thoroughly ignores the parts that don’t relate to the end, especially the parts that say he can’t predict the end.
It’s not about biased vs unbiased, it’s about reading to read and reading to confirm.
