People behaving badly

What is the appropriate response? How does one impose restraint? A show-off cannot be shamed and inattention may prompt an increase in effort. I do not have an answer. Responding in kind is definitely not appropriate, though the temptation is great.

The problem with authoritarianism is not the fake authority, but who idolize and worship it. Worship is a frivolous enterprise. But is frivolity a defensive response to abuse?
