Britain? European? Britain was always caring about it's own interest and since Hundred Years War it was mostly concerned about Europe when it was needed to retain British influence over european matters. Without EU Britain will be able to have independent foreign policy, independent economic policy and won't be colonised by immigrants (and I know that Poles are one of the largest groups of immigrants, thank you very much, no need to remind me that). It stands in unique position to be a link between USA and UE. Britain is also a birthplace of modern democracy and doesn't really fit anti-democratic EU.
Britain shares most of the elements of European culture as well as the tradition of liberal democracy and human rights (and we're certainly closer to Europe economically and socially than we are to America). There is also hardly a single European war since the end of the medieval age which Britain has not been involved with. We have always been heavily involved in European politics, diplomacy and war. To claim otherwise betrays an astounding ignorance of history.
We have an independent foreign policy (did the Iraq War and the Libyan Intervention somehow escape your notice), we have an independent economic policy (hence why Mr Cameron and Mr Miliband both argue with each other about the economy instead of wringing their hands and pleading with Brussels to do something) and in terms of immigration there are about as many UK citizens living in the rest of the EU as there are citizens from the rest of the EU living in the UK (and the largest group of Britons living abroad are pensioners who are a drain on health, social and pension systems as opposed to the young, healthy, taxpaying, non welfare system draining workers who make up the majority of non-UK EU citizens living in the UK).
Britain is indeed ideally placed to be a link between the USA and the EU which is why the US has expressed before that it hopes the UK stays in Europe as a key player in the largest economic superpower on earth instead of withdrawing to become a small, declining, insignificant island in the Atlantic without influence.
And, as I've said before, any analysis of structures shows that the EU is just as democratic as the UK, if not more, with an indirectly elected upper chamber, a directly elected lower chamber and a government dependent on the lower chamber for its existence.
P.S. The UK is predicted to overtake Germany as the largest economy in Europe by 2050. Why? Because the UK has an increasing population and better demographics thanks to immigration compared to the rapidly ageing and declining German population.
