There's one older Swedish lady who lives here who comes along to our "morning singing" (yes really, it's a thing, and it's compulsory. We basically sing "spirit songs"),

It might actually be based on monastery practices...

I helped facilitate that for her, but the other participants laughed at her (like, "What does this crazy broad think she is doing?"), and then the organizers basically pushed her out of the room...

So the participants are also literally insane?

During that, they started actively threatening harm to me, lol.

You better have recorded that.

So yeah, after all this, I've started organizing to leave this weekend, or early next week. I'm done. That was the final straw.

Good. Staying in Sweden isn't so great that you should tolerate this.
