If it were limited to "when you do blah, I feel blah" verbiage, it would feel like that. But it's more generally about taking accountability for one's own side, while listening to the other side, without needless escalation. I can't really see a flaw with that approach, other than it taking more work.

I wonder how many arguments would be defused if both sides could phrase the other side's point of view in a way they would agree was accurately stated.
