History is nuanced. The connections between what happened historically and the way things are now, are nuanced. Will anyone claim that President-Elect Trump has a nuanced understanding of the ways things are and the history of how they came to be that way?

Tweets are not nuanced. You can express a provocation in 140 characters or fewer, but you can’t express a concept, much less a nuanced concept. That’s why some people are tweeting in chains. But that too is a poor substitute for rational discourse.
