It seems from those I have encountered with recent literary degrees that The Hero’s Journey is being taught in colleges as a literature class. It occurs to me also to say that in all fairness some of these newer students of the topic are merely repeating what they have “learned” in their classes. Sad but true. But then again, like you and James, I tend to be a traditionalist.
Oh, but then I do have to add that I know some students who have taken these classes in their literary degrees on The Hero’s Journey who have written on it in a way that probably Campbell would be happy and proud–which for me is heartwarming.
