If you can address a conflict in person, do it. Handling problems in public or in groups always makes things easier. Courts don't allow evidence to be used without first being inspected by both the defendant and plaintiff. This is for good reason.
The cost of public humiliation doesn't only humiliate the humiliated, it humiliates the public. Everyone has problems. Everyone knows everyone has problems. Those who deny their own problems stir the public into lynching others. But, that's when the public accidentally lynches the Hunchback.
Publicity trump cards come at a cost: They make matters worse. Talk in person.
