Mainly anecdotal but it seems to me that it is a common representation worldwide of the French to be arrogant and very proud of their own culture. I'm trying to not make a judgment here, not that I'm saying it is good or bad.

Anecdotal also, but I work internationally and with a lot of french people. The French groups would be the most vocal to complain about pretty much everything in their host country, claiming they cannot wait to go back to France to taste "Real bread", or "Real wine", etc etc.
