I have seen this joke made about every president since Reagan. It just gets recycled over and over. It’s like the sun rising in the east in the morning. Nothing to get your knickers in a twist about.
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.
