Maybe ask the people who posted it on Discord?

If you do get an answer, please post it on here, as I'm honestly interested in knowing how to trigger such an event myself.

Not worked.

What "Not worked"? Could you please elaborate?

I followed the way discord told(integrate the ghouls and be afraid of commies), but couldn't trigger this event.

What I meant was that you send one of them a DM or ask them somewhere else.

I don't know how to do it exactly but this is what I done which propably triggered it. First once creating Granite's personality you need to make him hate the communists (give him the anti-communist trait), then you need to do the Anti-communist propaganda focus, and finally after that need to accept the ghouls into society by doing a specific focus. The event should pop-up some time later. You can choose to make Granite read "Das Kapital" or to execute the "Ghoulish librarian".
I'll just say at the end that I had quite high legitimacy (around 60%) and I still haven't found the United States (gone into focus that aims to restore the United States).
Some events may just pop-up at random, you might need to play this mod few times to actually see that event.

thanks for bringing this to my attention
