My apologies, davem, for an overly long post difficult to follow.
I must say I did not write out of any desire to flaunt my particular small area of training. We all come to Tolkien from our own perspectives and values and, I think, our relationship to/with him and his work is not necessarily uniform or unchanging. I first devoured The Hobbit and then LotR as a teenage infatuation with all things fantasy and then had the great pleasure of discovering Tolkien's 'serious' side when I studied Old English. An unexpected bonus!
I really felt that there was a very strong conflict developing between the issue of the freedom of the reader and the authority of the author and what I had hoped to do was provide some clear and extensive points in favour of the reader's experience--points made not simply as personal preference and opinion but as evidenced in a critical perspective which traditionally had ignored Tolkien but in which I hoped to suggest he could be included.
I think Germaine Greer has an animus with more issues than just Tolkien.
Enough for one late night!
