Depends on the point they are trying to make, I guess. With all respect to Her Majesty, this did happen and perhaps the media in the 1930s got things wrong by being as deferential as they were. For example the Wallis Simpson story (apparently) took ages to break over here, as the newspapers decided to gag themselves over it. Which was, perhaps, a bit silly given that newspapers and media everywhere else (mainly the US) were full of the story.
My understanding is that this was quite typical of the British in the 1930s anyway. A fair number of people at all levels of society supported Hitler, or at least sympathised with his views, in the run up to WWII. I'm not quite sure when the turning point was. Possibly when he broke the terms of the Munich Agreement?
