Absolutely. If this were a majority Brit forum, a thread like this would have started with the Scots and the English mocking each other, then the Welsh having a go at the English, then the North and the South of England mocking each other and being dismissive of Wales, then North and South Wales ditto, then neighbouring counties casting mutual aspersions, and finally two adjacent towns being rude about one another. And I can even think of a few English towns where different districts say uncomplimentary things about their neighbours.
