The only claim of a moral highground here is implicit in that shitpost of an article.
However, it raises an excellent point. The United States is not going to get anywhere if half the country looks down on the other half as a bunch of plebs, and in response the "plebs" disdain the elites. (I understand that this is a gross simplification, but I have seen this attitude often enough that it is significant).
For me, the article was about the need for mutual respect.
Ironically, the people who are going to take it most directly in the tuckus, are the people who voted Trump.
