Oh and the "hate" i believe that there is some anti-english behaviour from some quarters but it's the in England. I lived there for four years and saw a fair amount of anti-Jock behaviour.
I also think that there is a fair amount of media hysteria (just see the Culcutta Cup match a few weeks ago, it was pretty nationalistic on both sides and repeatedly talked of the Auld Enemy).
