Vincent,
You pointed out a very impressive and topic argument.
But first of all I want to tell you that my grandpa was twice in Ellis Island, in 1911 and in 1920. My father left very soon is place of birth and lived is all life far from it. My brother is right now overseas... Sorry this certificate of family status of mine, but in a certain way, maybe, I can get closer, if not understand, that sense of proudness you’re talking about.
But you’re right I was born and grow up in Italy, in my hometown and I can cultivate it without any negative reverberation on my life. This is a privilege.
But to meet stereotypes, if of this we’re talking, we don’t need to go to a contest, or to talk about aviation... just switch on the TV, or open the most of newspaper.
Cross referencing is not that bad when you’ve something to cross.

Mistakes in spelling or wrong plane identification are part of the game, from both side. Even the two episode of Damiani and Quaranotti you wrote about are and remain episode, it does not matter the bad or good faith of the actors.
And in a smaller scale the same episode of Greenhous you just mentioned happened here: SuperAereo doubted (don’t know in which terms, but I know him as a kind person) about Lucchini score and we had an uproar
In the end I’ve to say that I totally disagree with your idea of the Regia Aeronautica biggest obstacle...
I had the opportunity to meet some Regia vets and according to their memories their lack of tactical training, of gunnery training, of appropriate machine were reasons much more felt than any kind of a totally unknown racism (and consider that in all of their memories the relationship with American pilot was something very close to the brotherhood).
ciao
