My wife is a born and raised British citizen Spend 10 seconds with her and you would know where she is from. She lived in America with me for 10 years before we moved to Spain. She can’t recall ever being accosted by a stranger offering their opinions on British politics, their leaders or even the Queen. So why do you expect me to put up with jokes and insults from people who don’t even know me, just because I have an American accent? Perhaps if more people got their knickers in a twist they wouldn’t think they had free leave to dump on us. They won’t get a pass from me.
You should get your knickers in a twist.
note though - WHY do people from Nottingham to Nairobi have an opinion on Trump and the USA? While they won’t have an opinion on Wales or Ghana?
Because the USA matters.
The USA matters to every country on the planet. Trump sneezes and people get affected - the USA puts a trade lock on China and Paraguay gets affected.
The joke you stated is just stupid and ignorant.
