Only been to the States twice, visiting my sister's family who live in Iowa. When the immigration desk officer saw our destination, he said "Waterloo, Iowa? What the hell are you going there, for?"
We were treated with respect and welcomed wherever we went, even given credit for walking most places, rather than climbing into a vehicle for every journey.
I think that what rankles most with Brits is that our society, more or less slavishly, cherry picks and emulates the very worst US practices, such as litigation laws. We don't do the sensible things, like give discretion to home owners to defend their family and property against violence and intrusion. We watched in wonder while the USA elected ********* like Clinton and Bush, then did exactly the same thing ourselves. We envy the fact that Americans have maintained a reasonable standard of living, but we insist on keeping one of the most expensive welfare states in the world, so much so that a huge number of migrants are keen to cross some of the oldest and most established civilisations in the world to get to us.
I'm immensely proud of being British, but largely for historical reasons, rather than because of our modern society. I've trogged around the WW1 cemeteries and seen the evidence of Britain's right to a place in the free world and we still do our level best to support the rights of free men and women everywhere, but having been part of the means for several years, I would say that.
Truth is Britain is not geographically isolated, does not have much in the way of raw materials and, apparently, needs to get on the the rest of Europe. I suppose it's better than being at war with them.
Anybody who thinks that the average voter in the UK is any more knowledgeable than the average voter in the US is going to be very disappointed, not least because many UK citizens vote traditionally, rather than on the issues.
