>This goes back to something I mentioned here before - that for some unknown reason a lot of people in the USA seem to think that if you're for one thing, that means you must be against something else. You can't be pro black-lives-matter and pro-police, you can''t be against a war and still support the troops, and apparently you can't say America does some dumb things without being labeled anti-America. This dim-witted thinking keeps people from finding things that they see eye-to-eye with someone and instead just view them as an adversary - when in reality, for the most part, they really want the same thing. I've wondered in recent years is this is primarily a cultural thing unique the us USA or if there are people like that everywhere. My uneducated guess on the subject is that while it's not unique the USA, it's a hell of a lot more prevalent here that any many other countries. but of course that is uneducated guess as my foreign travels are not only very limited, but also were a few decades ago.
I read this last night, which I think addresses your main point:
