Obama, Cheney and Bush are war criminals under international law and Trump isn't, but boy when Trump is rude to someone, there's no end to the condemnations that he's the worst person ever, despite being the only president of the past 30 or so years who didn't start a war. Even crazier, those war criminals are now all darlings of the Democrats because they trash talked Trump.
Trump and the way the media played on his craziness for ratings really broke people's brains. I wouldn't want that buffoon as president either, but really, get some perspective. He wouldn't be nearly as appealing if politicians weren't almost universally awful and self-serving, but because that's normal and they're "polite" about screwing you over, well that's just fine and dandy.
Which is to say, while I take your point about the relative morality of large scale leadership, having lived through all the folks you mentioned and more, that Trump’s naked pursuit of personal scores with public resources was unprecedented in my lifetime. Society is a shared illusion, presentation matters, and boy did his coarsening of that conversation have far-reaching consequences.
