What is the problem with this? What is wrong with the discourse of the Internet comments section? The rhetoric of common people?
For starters, I would deny that most people would have anything to do with such revolting garbage in their own lives. A guest at your dinner table like Wolf who profanely attacked other guests would be politely (or not so politely) asked to leave. A neighbor who ranted like Trump about Mexicans and the FBI would be avoided like the plague. And yet people whom we could not trust to behave in civilized company now dominate American public discourse. It is something Wolf would immediately recognize: a sad, sick joke.
But the problem is deeper, for one main reason: because good rhetoric is the carrier of serious thought. “Eloquence,” said theologian Lyman Beecher, “is logic on fire.” A great and memorable phrase encapsulates an argument. “The world must be made safe for democracy” expressed Woodrow Wilson’s vision of America’s role in the world. Kennedy’s “Let them come to Berlin” summarized America’s commitment to containing the Soviet Union. The Rev. Martin Luther King Jr.’s “I Have a Dream” speech grew out of a compelling conception of fairness and justice.
