It just seems to me that it's considered acceptable (and not Naziesque) for people of pretty much every ethnic group except for English, to want to have some sort of "pure" form of their culture. Now, I think I can understand why that might be, but I really don't believe for a minute that everyone who would like to preserve a pure form of English culture is doing so for reasons that could be compared to the Nazis.

I was once in a session with some people from the UK who strenuously objected to the idea that the music of O'Carolan could be considered Irish. They said this was because he had studied classical music in Italy. Nobody accused those people of being of the same mindset as the Nazis.
