"Even as high as DH5 we still sometimes see deliberate dishonesty, as when someone picks out minor points of an argument and refutes those. Sometimes the spirit in which this is done makes it more of a sophisticated form of ad hominem than actual refutation. For example, correcting someone's grammar, or harping on minor mistakes in names or numbers. Unless the opposing argument actually depends on such things, the only purpose of correcting them is to discredit ones's opponent."
How do you measure the spirit? An author may detect bad spirit everywhere and take all DH5-but-not-DH6 disagreements as effectively DH1.
Anyway, the quoted paragraph seems very harsh on many small-point DH5 disagreers. Some people just feel the "duty" (xkcd.com/386) to correct mistakes, without being deliberately dishonest. And there is a lot of uncharted importance space between grammar mistakes and the central point. As an example, what if the central point were correct and worthy but illustrated by two examples, one of them bad? The argument doesn't depend on it, but is it still clear that the only purpose of correcting the author is to discredit him?
Why not generalize DH6 from "stating the central point and refuting it" to "refuting a point and commenting on its importance"? Then you could even correct grammar mistakes, just add explicitly that you're aware that as a grammar mistake it's minor. DH6 would no longer imply power or effort, but, as pointed out in the essay, it already doesn't imply truth.
