I've just stumbled on this bit that seems relevant to me:
Insist on using objective criteria
The final step is to use mutually agreed and objective criteria for evaluating the candidate solutions. During this stage they encourage openness and surrender to principle not pressure.
I find the concept of "pressure" very relevant, and I like the idea of discussions being guided by content rather than pressure.
I'm exploring the idea of filing under this concept of "pressure" most of the things described in code of conducts, and I'm toying with looking at gender or race issues from the point of view of making people surrender to pressure.
In that context, most code of conducts seem to be giving a partial definition of "pressure". I've been uncomfortable at DebConf this year, because the conference PG12 code of conduct would cause me trouble for talking about what lessons can Debian learn from consent culture in BDSM communities, but it would still allow situations in which people would have to yield to pressure, [[as long as the pressure was done avoiding the behaviours blacklisted by the CoC|correctness]].
Pressure could be the phrase "you are wrong" without further explanation, spoken by someone with more reputation than I have in a project. It could be someone with the time for writing ten emails a day discussing with someone with barely the time to write one. It could be someone using elaborate English discussing with someone who needs to look up every other word in a dictionary. It could be just ignoring emails from people who have issues different than mine.
I love how the Diversity Statement is elegantly getting all this where it says: «We welcome contributions from everyone as long as they interact constructively with our community.»
However, I also find it hard not to fall back to using pressure, even just for self-preservation: I have often found myself in the situation of having the responsibility to get a job done, and not having the time or emotional resources to even read the emails I get about the subject. All my life I've seen people in such a situation yell "shut up and let me work!", and I feel a burning thirst for other kinds of role models.
A CoC saying "do not use pressure" would not help me much here, but being around people who do that, learning to notice when and how they do it, and knowing that I could learn from them, that certainly would.
If you can link to examples, I'd like to add them here.
