Every time I put it to a JW on a cart that they are creationists they take offence. You have to explain the difference to them between old-earth and young-earth varieties of stupid.
Even at that, cofty, they are a weird hybrid of young earth/old earth creationists. They sort of kind of are willing to admit that dinosaurs and such lived 100,000’s of years ago and that earth is eons of time old, but also twist into pretzels to make it all fit into the model that globe was wipped out with a flood 4k years ago and ignore the geological evidance of that.
