(I was once watching the semifinals of the women's epée nat'l championships, and a former Olympian told me that "B always does the right thing, and that's why she won't win: A knows how to do the wrong thing at the right moment, and that's why she's a champion")
wrt to https://news.ycombinator.com/item?id=42216196 : my impression of non-human violence is that they are better than we at avoiding violence when the power balance is clear; it's mostly with young animals or moments where the status quo threatens to have been merely a stasis quo that application of violence becomes necessary. (compare Cherryh, Foreigner)
