As far as the article's concerned, I'm not at all convinced this is a major issue. Its very hard to give serious credit to European politicians arguing for their respective national cultures and identities - virtually every country in Europe is a confederation of smaller nations and dukedoms and principalities. Many of them have multiple officially recognised languages. Many have multiple thriving regional dialects. Many regions within the same country have radically different customs, beliefs, attitudes, cuisine, even religions. Many of the current European states were politically created entities with less than 200 year histories.
