The European debate in the UK is rather odd. It is portrayed as one of two stark choices IN or OUT. If an in/out referendum were to be held tomorrow I would suspect, based on what my friends and family say, that most of the voters of Wales would vote OUT (not a scientific survey, but this is a blog not an academic essay).
The oddity is that most people who tell me that they would vote OUT are not anti-European; they are opposed to a European Superstate. They agree with the idea of a Common Market, they agree with the idea of a "level playing field" where employment rights or animal welfare standards etc are equal thoroughout Europe they like the idea of free trade and free travel in Europe; what they don't want is an United States of Europe.
Such attitudes are not "little Englander" attitudes, they are not UKIP attitudes; they are actually Pan European attitudes. Large numbers of the citizens of every part of Europe want to rein back the idea of a European Superstate and re-embrace the idea of a Common Market. Supporting either the Europhobes or the Europhiles in an UK stark choice referendum will be bad for Wales. What we should do is unite with those, thoroughout Europe, who want a new European settlement where independent nations are In Europe, but not under Europe's thumb!
