vyper, no is trying to steal your culture away.. If it has diminished, its due to the people who belong to it, not anyone else. This is excluding the Americanization, via McDonalds (oh the irony) et al, because the whole world has that..
The EU is a political and economic body, and to some degree, a judicial one. Scotland is no more a tourist attraction than any other European country. People travel from country to country, exploring different culutres and peoples. Thats a good thing, it allows people to understand the world around them, and that helps to comabt ignorance.
Do you have such an identity crisis that you would cling to whatever national identity you can scrap together, even if its taking pride in the Empire. Subjugation, murder, exploitation, you know all that. Oh and, if it'll make you happy, the British government is trying to reform schools to teach kids more about the Empire, so there you go.
If you're so worried about perserving your culutre, I suggest you pick up a claymore and get started

:D Do something about it. Hell, Scotland has tons more culuture than Serbia does, but I still don't feel threatened. You guys have thousands of years of history, Robert the Bruce, kilts, bagpipes and so on. We (Serbs) mostly have food and a few funny dances. But no one can make me be less of a Serb. I've been living in Canada for most of my life, even more so if you consder that for 5 of the 8 years I spent in Yugo, I don't even remember.
Perservin your culture is, I would say, a worthy effort, but it has nothing to do with the EU..
