When you read the books as a child, watching Hagrid give Dudley a pig’s tale is hilarious; when you read them as an adult, you see Hagrid as (at best) a child abuser, convincing his parents that their fear and hatred of the wizards who have forced themselves into their lives is amply justified.
I’ve never thought of it that way. But yes that does make sense. I can see how that would look to Dudley’s parents.
