I think "us vs them" mentality is the point here. To demonstrate "them" are so irrational, so deplorable, so beyond any redemption and lacking of any sense and virtue that their alienation and complete disregard for their needs, voices and concerns is justified and is the right thing to do. If somebody just wants the world to burn, you don't discuss a compromise with them that would be acceptable to both sides, you put them in jail or mental hospital. The author doesn't want to find common neutral ground with the deplorable Trump voters. He wants to convince us they are so crazy that "normal" people should just shun them, avoid them, treat them not as rational people disagreeing on politics, but as people afflicted with NFC condition that just are that way, and that's it.
