As a minor aside to McGrath's letter (and not as an error correction, for the wording is careful enough in that sentence):

The citation often attributed to Goering (you may also find attributions to Goebbels) originally comes from a book by Hanns Johst, a Nazi writer. Goebbels or Goering or both may have cited it more or less approvingly. As far as I know the original wording is (in translation): "When I hear the word culture, I release the safety catch of my pistol".

As I said, a minor aside remark not meant to detract you from your your fight.
