Here's one I just had a brain fart

Delusions of grandeur - a false impression of one's own importance.

If we break it down to whats salient in the definition of "delusions of grandeur", importance would be the key. Defined it means "the state or fact of being of great significance or value."

Is Trump important? if we ask doctor google or in fact most of the known world, in fact just the question "Why is the president of the US important" we get a snippet answer of "The president directs the foreign policy of the United States, making key decisions about how the United States acts toward other countries in the world. The Constitution makes the president commander in chief of the nation's armed forces. ... Congress and the president share the power to make war."

I don't understand how then we can state Trump has delusions of grandeur

I think your post is good in that you have written a whole lot of words and used emotive language to stir the pot. But substance and actual value I think its only worth as much as the upvotes its got as opposed to making a real change towards something positive. Especially when it leans towards being "reverse racism"
