Well in my mom’s defense we lived one town over from the Wyley Gates case (a teenager who killed several family members and supposedly planned it via D&D)…so our community and local religious leaders etc were a bit worked up over it.
But my brother did a whole research paper and presented it to my mom (who was a teacher at the time) and he eventually effectively argued to get his game pieces back (little did she know he still had the books etc!)
