I had to chase down your clue there:
Opposition to Willy Wonka was led by a Canadian woman writer who moved to California and was taken in by the liberalism she encountered there.
None of her writing became especially famous, save for her attacks on Willy Wonka.
Your link was good, but still essentially cheery, while the opposition to WW was relentless and very, very bitter.
I can’t remember exactly what Dahl did to show his very deep conservative streak, but it was something important; the libs hated his guts for something ideological.
This made me like him much more. Plus, he was a fighter pilot, which is cool.
They hated Jack London’s guts, too.
