I don't know anyone who says America was perfect before Trump came along, although a. There's a lot of rose coloured reminiscing about Obama and b. An awful lot of Cold War era Western/free world boosterism still floating around.
No, obviously I was embellishing the point for effect, but whenever I hear these kinds of remarks, my first reaction (regarding those who make them) is "where have these people been?" This points up just how out of touch a lot of people have been in recent decades, leading to the very problems which led to Trump's election in the first place.
Over and over again, I see threads where people express incredulity and bafflement over Trump's election, and the bottom line is, they have no answers. They'll come up with all kinds of bizarre theories, from alleged Russian interference to right-wing propaganda, as if large sections of the country are nothing more than zombies being controlled by some mind-control device.
This is another indication of just how out of touch many people are, and again, they can't seem to figure out what to do about anything.
Now sure, I acknowledge that most non-Americans don't know every single little thing going on there, and of course there are cultural differences that cause some misunderstandings about some stuff. Butcwhen you have a really serious problem, like Trump, "oh, you don't understand, you're not an American " holds less water.
But the thing is, Trump, in and of himself, is not really the problem. Trump is a symptom of a deeper problem which so many people fail to recognize. That's what takes a bit more understanding and empathy, which is just another way of saying trying to walk in someone else's shoes. I know Trump supporters and I know for a fact that they're not the illiterate, uneducated, ignorant idiots that so many people would paint them as. That's how I know that so many people simply don't understand.
Consider; you didn't need to be a German in 1935 to know Hitler was a serious problem. You didn't need to be Iraqi in 2000 to know Hussein was bad news, and today, while non Americans might not catch every subtle aspect of everything that's happening there, you don't need to be an American to see the general trends around Trump.
This may very well be true, although it's not really that difficult to figure out how and why someone like Hitler could have gotten into power. If they didn't recognize the problems in Germany in the years immediately following WW1, then they might have believed that Hitler was just some kind of bizarre demon who simply popped up out of thin air - which is how a lot of our popular culture portrays the history of that era. Again, it's simply a matter of being out of touch and unaware of the causes and effects of history - a common malady which continues to this day.
