@oblomov some impressive analysis, thank you. Found via boost by @plutarch
I looked before at the phenomenon, and with an eye on fostering inclusive and cohesive online socio-cultural environments, relating to Social experience design (SX) practices.
A concept in #SX for instance is #CALMCulture which stands for inclusive culture in Constructive activism-led movements, whereby the activism doesn't stop by awareness-raising but follows up into a solution-oriented process. Tries to attract, engage, and activate people for the good cause. I see a lot of activism on fedi that is more likely to backfire by how confronting it is, or 'sacrifices' it demands in the call-to-participation (a call to conformance), or it has become more performative for an in-group of peers, echo chamber activism. Many anti-patterns come into play, most prominently the purity spiral.
That's tangential. Part of that exercise I defined the more #inclusive terms #ReplySigh and #Oversplaining as SX common language.
