However, fundies and born agains operate in a way similar to Islamicists: "infidels" (IE non born agains) are not entitled to the truth. This has been highlighted about Muslim Jihaadists: they'll lie in any way possible to defeat the infidel.

So he'll fuck you over and feel principled and holy about it while doing so and consider it your due. I've known a LOT of Christians who operate like this. IE, contracts and agreements don't count.

Don't fundies regard the words of the bible as higher than anything else?
If so, they're objectively wrong in the behaviours you describe because those cannot be squared with "love thy neighbour as thyself"
