Well then, I must bow to the voice of experience from one whos perceptions I trust.
My mum was born in Vancouver, but her two sibs lived in the US and were US citizens. My aunt was married to a career US Navy captain whose career began in the1930’s in China. He was a staunch Republican. (until Reagan pissed him off by reducing his pension) His wife, my Aunt went to Vassar and was a staunch Democrat. Mum’s brother went to Harvard and was a Liberal New York Democrat.
There were lots of cousins, of whom I met a only a few. All were rich and all were quietly Republican with conservative views. I formed part of my opinion of the US from them.
Probably the most powerful influence on my opinion was the attack of 9/11. I remember vividly standing in my lounge room watching it on TV. I was horrified but not all surprised.
Nor was I surprised at the collective US nervous breakdown, which led directly to the Invasion of Iraq. The resulting Patriot Act and formation of the Department of Homeland Security made me decide not to visit the US again. The cherry on top has been the obscene numbers of mass shootings about which the US as a people have done nothing.
I was also influenced by Gore Vidal, who I consider one of the US’ greatest public intellectuals of his generation.
I need to add that with a single exception***, my experiences in the US were positive. I was treated with kindness and civility by everyone I met, from relatives to casual encounters with New Yorkers.
The only thing I can conclude is that my view is macro, yours seems to be both macro and micro
***the one exception was an officious US immigration officer at JFK. ( I think) He had formed the unfounded belief that everyone who comes to the US is simply dying to live there. He was quite rude.
