Fallen Empire Threat of War Threshold

[Wombats O' War]

The Stellaris Wiki says at below -75 relations, FEs will start threatening you with war if you don't accept some demands. Is that still the case with Utopia?

A Fanatic Spiritualist FE spawned very close to my Fanatic Materialist robot-loving nerds. We're feeling jittery...

I will note you'll be fine next to Fanatic Spiritualists. They just get upset if you colonize a holy world. The Fanatic Materialists are the ones to watch out for.

Sadly I'm not sure about your question. My last game I actually settled a planet too close to the xenophobes and had to abandon it. Had someone that hated me up north and didn't want to risk a war that would wipe out my fleet and destroy my infrastructure. So I'm not sure on the threshold, as I usually keep my tail between my legs until I get strong enough to fight them.
