@LindyLou2020 , no worries. You gave some excellent insight into the 'sour grapes'. Your situation: daughter living in the US with US in-laws is a great window for the armchair cowboys on MN.
This sentence describes it well:
'There seems to be a weird British delight in stridently running down and criticising America and Americans, and of course it has its vile aspects, just as everywhere has, including the UK.'
When Bush and Trump were president, there were constant jibes. To be fair, in UK presentations, there are pot-shots at the French and whoever else is in the news at the time.
I doubt any presentations in the US reference the UK PM and probably not negatively. In my experience, in the US, any reference to the late queen or any member of the UK royal family was/is positive.
To me, it feels like sibling rivalry: the US is the younger sibling and doing well so the UK has to get in the last word and or play down any success or condemn 'childish' behaviour. That's sour grapes, innit ....
But there does seem to be more admiration or at least toleration for Anglo South Africans and for Aussies. And I don't see many threads bemoaning gun violence in South Africa and offering political advice.
I would never try to say that the US is perfect or some kind of Nirvana/Xanadu/Paradise - nowhere is.
But most Mumsnetters who live in the UK would be extremely offended to see a thread like this, full of opinion based on personal feeling, discussed mostly by people who have never even been to the UK and have no direct connection to it, about a hot-button issue like Brexit (those few in the US who have even heard of it think it was totally moronic to leave the EU).
Also, as nasty as Brits can be about the US, they should remember that most in the US neither know nor care who is PM. Ask them and many would say Tony Blair or Boris Johnson. This is what I remember when the presenter makes a mean, not very accurate joke, in a presentation: for all that the UK agonises, obsesses, about the US, most in the US don't even think about the UK.
