No, I will in part stand up for cowtipper viz Chris.
Overall the problem is that stereotypical folk travel and make the image problem worse - imagine what we Brits come across as in the US. Boorish, overbearing, intellectually superior inc humour, bad teeth, uncoordinated dress, moaners.
I have, twice in a Parisian restaurant with friends (one of them with a fellow Brit), spoken nothing but French to avoid giving the impression that English was tmy base language. Once was with a Brit group of six and the other with four Americans. No attempt to even say Bonjour, issues over the food and wine (sweet wine with steak in the latter case) etc. None of us travel well as a nation - look at our German cousins for stereotypes....
Over there in the States you can easily break the stereotypical perceptions Chris refers to. I speak as someone who has lived over there for several years. For example in response to some of Chris's points, but not all...
(i) overweight - walk the streets of the UK and we are going the same direction. On the US streets there are a lot of very svelte figures as fitness is now more ingrained than over here
(ii) pushy - more prone to speak their mine and clear their chests rather than moan and sulk - but not all Americans are like that at all.
(iii) loud mouthed - there's psychology on this and one of the major elements is the space that they have to move around in - we are all crammed in as a nation and hence over in the States, more space between couples whe they talk, the table etc etc
(iv) irony,satire and humour - its very much on the increase over there but there is a point that a lot of it flies right over their right shoulders when you use irony. Television humour is improving as well from things like Boston Legal and programmes like Cheers and Friends aren't bad, plus some good stand-ups emerging.
