Notwithstanding the farcical opening gambit of the OP, threads like this make me sad as they develop.
I'm uncomfortable with this now increasingly common, vehement rejection of being part of something that bit bigger and more diverse - A hatred of anything starting to resemble a group, or a coalition of smaller tribes, a family of peoples with lots in common, or, a union, if you will. It occurs to me that this small country / county mentality must surely be out of place in the modern world where we're all travelling more, where we're increasingly working with foreign people, naturally starting to increase our understanding and acceptance of "foreign" cultures. It's all a bit last century, a bit "he's not from round these parts". I love and value the different cultures of the Scots, the Irish, the Welsh, and I love going there and working there, but somehow it's becoming the norm to reject and hate your nearest neighbours? It's odd. We're becoming more insular, more blindly patriotic to a small country, some even blindly (and for no good reason) patriotic to a county for goodness sakes.
Like Julia, I'm also a bit uncomfortable with this notion that where you're from is something to be gleefully and blindly proud of, like you achieved that fact by your own toil and endeavour. You happened to be born there. That's all. It doesn't make you brilliant, or better than other people by dint of geographic location of where your Mother happened to be when you came into the world.
I'm from the UK, I'm British, and I'm alright with that. (I'd like to still be European too, but that's for another thread).
For what it's worth I'm English (Manchester) born, but left there at 17 and haven't really stopped moving since. I have Irish parents and families on both sides, I'm married to a Scotswoman, and our daughter was born in London. I'd rather celebrate and enjoy all of that, rather than go around harrumphing that I'm "proud to be Manchester born and bred", for whatever that might mean.
