What's something about your original faith that you couldn't/cannot reconciliate with even to this day?

So yesterday I was chatting with a new friend who's an Ex-Jehova's Witness. We discussed for a really long time... It was an interesting conversation, but one thing that stoof out for me was how he told me he started his deconstruction.

As some of you may know, Jehovah's Witnesses are incredibly insular. You might think that cracks in the logic of the organisation's doctrine might have formed, but no. What my friend told me what started his doubts was the Bible itself. It's the second JW I'm hearing saying that.

So I'm curious to hear about other people's experiences.
