Gromit
I thought it strange when I read your opening passage to this thread.
Gromit a known anti-British, anti Royalty ABer, seemingly being sympathetic to her majesty, but then his true feelings finely came out..
/// Edward VIII'A Nazi sympathies have been well known for decades.
So the interpretation that this was mockery of Hitler is somewhat kind.
I doubt it was mockery. ///
Surely this is just another 'non-story' as you often accuse some other's post as being?
