Dead serious, sadly.
I’ve gotten in a lot of religious spars with guys that really come on strong as serious bible scholars only to find out that they are the real world equivalent of John Goodman in The Big Lebowski.
And when you actually look op the things they say are not really in the bible, THERE THEY ARE. I don’t get it. Especially with google and all the bible study sites, ridiculous claims are really easy to vet.
So why make them?
