Pap. You really are too sensitive about these things.
Stereotypes are rooted in truth, my own personal experiences back them up entirely. Having done some work at Jaguar Hailwood and having dated a scouse girl (and met her family) they do moan, are quite focused purely on their own area of the country and are extremely defensive regarding outsiders perception.
But, you know what, who cares!? All areas of the country have their quirks. Yorkshire is just as insular, the midlands just as whiney and the Skates have a massive chip on their shoulder too.
Cest la vie!
