I see no reason to “honor” Presidents or any other famous people when they die. They’re dead, so they can’t enjoy it. Though maybe leaders, performers, etc., while they are still alive, are enjoying dreaming about being honored, and maybe even trying to be more significant and effective in whatever it is they do, so they will achieve what they envision as a kind of immortality. But it’s not immortality. When you’re dead you’re dead and there is no passage of time from the point of view of a nonexistent being, because they have no point of view anymore. A passing second is as good as the passage of a gazillion years, and all civilization is as good died out and gone once you die.. But mainly I reject giving to one life any more honor than to any other just because they happened to have had notable success—or notoriety in the public’s eye. And people who are inclined for success were born with that ability, or into a favorable environment to succeed, or even with the will to work hard and succeed,. It was a gift at birth that they didn’t earn (because they weren’t around yet to earn that gift). Finally, I think all life is precious, or should be (and I’d include non-human animal life in that).
As for Trump in particular: No comment.
