Kano Jigoro was a very effective debater, and when he was working towards Japan getting the Olympics in the 40s, his debate style was called Verbal Judo in his autobiography. "Aikido In Everyday Life: Giving In To Get Your Way" is a book using Aikido imagery to label tactical conversation ideas. Terry Dobson was the author. My wife took issue with him openly adopting strategies like lying when you deem it expedient or necessary. The article seems to talk about verbal aikido in that vein.
Morihei Ueshiba was known for his kiai; I doubt anyone is advocating kiai to help with uncomfortable conversations.
To which I add: The Gentle Art of Verbal Self-Defense by Suzette Haden Elgin , 1980
