His focus on the monster being a monster and not misunderstood, and how that relates to real life abuse, is weighty subject matter indeed. I can imagine a more business-like editor nixing the inclusion of such subject matter into a game book, so kudos to the D&D team for allowing that viewpoint to be discussed by the creator of the material. His thoughts definitely have merit.
I read Dragonlance for years before I realized that Tracy Hickman and his wife were the true parents of my beloved Ravenloft setting. Talk about two influential people in the golden days of D&D.
