Something should haunt him. without ignoring everything else, Donny's opponents should hammer on one thing, maybe this, until he apologizes and fires people involved.
We need to prove to the world that he's not allowed to behave badly without having to address it.
But there really is an interference pattern. Whatever is happening is physical, not metaphysical, and is happening "through" or "because of" both slits at the same time.
Unless you're trying to argue that the statistical behavior of electrons is somehow decoupled from the behavior or each individual electron, which would seem to me to be a very odd metaphysical position.
Do you mean, "would they do something incredibly stupid because Donny insisted?" Yes, yes they would.
