Well, I’m not going to play the “it depends on the writer” card.

But it kinda does apply, even among people conveying their real life experiences. And, to forestall arguments, it doesn’t matter if it is objectively real or not, assuming they aren’t lying, they’re relating their lived experience. Whether that is a delusion or hallucination is irrelevant to this matter.

See, if you start off with the assumption that ghosts either exist, or are a form of shared delusion, then some things can be taken from that.

First, that anyone seeing a ghost is a minority because seeing them isn’t a common occurrence. Second, that regardless of anything else, the first ghost seen isn’t random. Third, that if a ghost can communicate at all (which is not a part of all reports about ghosts), it has limited time to do so.

With those probabilities in mind, if you see a ghost, chances are that it is there for a reason, that you seeing it is for a reason, and that it has to use its time with you to achieve a very specific goal.

Why would the racist ghosts start off saying “now, I’m racist, but hear me out”?

It’s that simple. Unless a ghost is haunting only a given grouping of people, there’s no benefit to expressing their racism at all. If they are haunting a race, then there’s still no need to outright say it; they’re acting on their racism and don’t care if anyone understands their motivations.
