It seems this "rhetorical nuke" missed Slog.

Let's fix that. Let's rewind—past Andrew Sullivan's rebuttal, past the contradictory evidence in the speeches—and listen again (or perhaps for the first time) to what it sounded like as the rhetorical nuke exploded:

The president is fond of referring to “the arc of history,” paraphrasing the Rev. Dr. Martin Luther King Jr.’s famous statement that “the arc of the moral universe is long, but it bends toward justice.” But with his deep-seated aversion to conflict and his profound failure to understand bully dynamics — in which conciliation is always the wrong course of action, because bullies perceive it as weakness and just punch harder the next time — he has broken that arc and has likely bent it backward for at least a generation.

When Dr. King spoke of the great arc bending toward justice, he did not mean that we should wait for it to bend....

The arc of history does not bend toward justice through capitulation cast as compromise. It does not bend when 400 people control more of the wealth than 150 million of their fellow Americans. It does not bend when the average middle-class family has seen its income stagnate over the last 30 years while the richest 1 percent has seen its income rise astronomically. It does not bend when we cut the fixed incomes of our parents and grandparents so hedge fund managers can keep their 15 percent tax rates. It does not bend when only one side in negotiations between workers and their bosses is allowed representation. And it does not bend when, as political scientists have shown, it is not public opinion but the opinions of the wealthy that predict the votes of the Senate. The arc of history can bend only so far before it breaks.
