With all respect and friendliness, @ChodeOfChodHall , certainly amongst the people I know, but even, I would hazard, in general, it's not about the Russians or any other national invasion (definitely not the Canadians lol). Gun ownership is a personal matter and rooted in the immediacy of bad neighborhoods and dodgy neighbors. (No doubt someone will come on to contradict me that in surveys Americans have said that they need guns to resist enemy takeover but that has not been my experience.)
Bears are actually a concern - my dad has chased them out of his garden. (FYI, news reports suggest that bears prefer beer.)
@LlynTegid - that is an excellent suggestion. Would the UK parliament be interested in voting that into law? Living in the UK, my sense is that MPs would not see that as a priority. No more than they would ban South Africans for the same reason.
After many years in the UK, I am still struck by the visceral response many Brits have to Americans and their ways even though there are many other places on the planet even less refined than the US. I am frequently in the audience for presentations and there is usually some unkind joke/comment about the US. My children have observed that in school, even if the video is full of good info, the teacher 'apologizes' for the narrator's American accent. It often just comes across as sour grapes.
The US is not perfect, but no country is.
