Anger is understandable but not accepted as the default.
To me anger is unacceptable as the default.
When or if it occurs we want to return to the default state (calmness) as quickly as possible.
Coming up with ways to stop us losing our default, accepted and acceptable state of behavior could be our ultimate goal. Preventative maintenance if you will.
This is not rocket science yet finding people that are willing to accept that their anger is not
acceptable has been a difficult task to date.
