And I could easily say I found greater ignorance in the north when I lived up near Chester (Shotton) for a few years. However upon growing up I realised that ignorance isn't a North v South thing. It's about how accepting an area is of outsiders. IE I liked Manchester (didn't like Liverpool though), found the locals generally to be very nice, although it maybe because I have family there so I'm somewhat biased.
I don't understand why so many people get so offended by their home towns being called dumps. Grow up!
To be honest when my hometown of Reading got listed in crap towns a while ago it installed a sense of pride. I come from a dump and proud, I currently live in Aldershot, which I like as it reminds me of Reading 10 years ago. The missus is trying to drag me out to Alton, but I can't think of anything worse than living in some semi-rural, cliquey middle class, Georgian market town.
I also go to South Bank Uni in Elephant and Castle and have friends in Grove Park South London, so all I've known all my life are places that are pretty ugly. To be honest I like Elephant and Castle for it's grit factor. You meet far more interesting people in dumps, I'd rather be talking to the local spiceheads about new world order conspiracy theorys, than middle managers about house prices.
