That is interesting. We don't talk about SD/self awareness/fighting at all actually. But then, I suspect that is due to a weeding process. Different kinds of weeding processes. Sounds like Crab is in the one that will push him out the door if he doesn't 'get the message'.
I'm not sure where you came up with this "half the lesson time" in 99% of TMA dojos is spent discussing how to avoid fights. I have trained only in very traditional Okinawan Goju Ryu and have never heard more than a few words spread out over 35 years talking about how to avoid fights.
Those who want to get in fights or lack the common sense to avoid them tend to lack the diligence and patience to train long at anything real. I have taught conflict deescalation as a Police Officer and during pastoral family counseling but it has never been necessary among my training partners.
