I have bashed Trump, not with names, but with things I thought were true. I do think he is sociopathic. He meets the criteria; look it up. However, like people, he has traits that are interesting, if not enjoyable. Sociopaths are great manipulators of people, bright, impulsive, excel in corporate worlds where dollars often speak louder than ethics, and love recognition and will even indulge in altruistic behaviors (but only when someone sees him do so). The other day he and his family members toured Mt. Vernon, Washington's home. I have been there (although I would have preferred to have visited Jefferson's Monticello, where his intriguing inventions, or improvements on them, could be seen; particulary the polygraph (not the lie detector), which when writing made a copy of what was written. He didn't actually invent it, but made suggestions to its inventors about its design.
Back to Trump: He was reported to have said, when touring Washingtons home at Mount Vernon, "You know, if Washington was smart, he would have put his name on more things; you've got to do that for people to remember who you are." To me, there are two elements of humor that I recognize: irony, that element found in Archie Bunker's malapproprisms and dumb remarks in which he unawares pokes fun at himself but which his audience is fully aware; and the other element being self-deprecatory or -demeaning in nature in that he knows he's no Washington, a man whose legacy has lived in people's minds generations, centures, after his time, without having put his name on anything, and Trump himself, whose name is plastered on buildings to napkins around the world, and he fully realizes his adeptness at branding will not qualify to live long a long life in the minds of future generations.
