“Dialectical” just means there’s a feedback loop. In fact I’m pretty sure the word “dialectical” is just “dialog” as an adjective.
If you take a dialectical approach to self-improvement, it means you view the problem as a self-reinforcing feedback loop between a person’s thinking and behavior and their external situation, rather than blaming everything on their thinking and behavior alone while ignoring where it comes from.
The dialectical treatment approach is to talk to the person to try to understand the feedback loop, then look for points in the loop where intervention is possible, not only in their thinking and behavior but also in their external situation, to yield a gradual improvement over time.
We need bait threads. Not only to lure out the worst offenders, but also to drive discussion that will reeducate everyone else. Purging isn’t enough. There needs to be site discourse, so that when someone points out misogyny, enough other people will recognize that they’re right to prevent a dogpile. Also people here need practice articulating why a comment is misogynistic, which will help with enforcement.
