Your excerpts go to the heart of the argument. If Orwell thinks it's nonsense to call Wodehouse a fascist, it's not because Wodehouse was necessarily above fascism. It's because he was too silly and stupid ("the events of 1941 do not convict Wodehouse of anything worse than stupidity") to even perceive it, a literal schoolboy:
As I have tried to show, his moral outlook has remained that of a public-school boy, and according to the public-school code, treachery in time of war is the most unforgivable of all the sins.
I don't know that this was fair to Wodehouse. The New Yorker article seems to take a more charitable view:
His resilient happiness, to me, remains heroic, and more essentially who he was.
My dad and I were struggling to explain the phrase "damn with faint praise" to a young relative a while back. This essay wouldn't have helped our cause because, well, it's loaded. But it is a master class in the concept.
