Hi Peter,
~sigh~ I could substitute 'Britons' for your 'American'. But that's OK (for the Brits.) As I said above, look to the mote in your own eye. It's easy, and frankly boring to go on about xenophobia, and I'm afraid coming from the UK, often hypocritical.
Errol Flynn was born in Tasmania. Obviously he was very unpatriotic not to go to Ealing but to Hollywood, maybe because it *shock horror* offered better opportunities?
I could find the same attitude on a number of British websites and box-tops, but, you know, life's too short.
No offence intended...
