When I write Responses I am mostly addressing other readers of the article. I realize that I often make authors feel that I am undercutting them in some way, but that is not my intention. If I think someone is wrong about something (based on my understanding of it), I say so outright. I definitely realize that I basically have nothing to add to your understanding of any topic on which you write, Dr, Giles. I do have an agenda, but my concern is a more just world, not any personal aggrandizement.
