And didn't C.S. Lewis say that those opposed to escapism are commonly called "jailers"?
That is quite the unsubstantiated dismissal, and I think this author got a lot less out of the teenager's literary canon than I did. Maybe the self-anger should be directed not at failing to read works worthy of serious scholars, but at failing to recognize that the works that were read were in fact worthy of serious scholars.
I will suggest to the teenagers reading this that reading these works in community is very important (and the fanfic community is a great one for so many of the works in the teenager's canon). If you only see your own interpretation of the works, and your own interpretation is primarily about family trees of obscure half-ogres, you're missing out.
