There are people who derive pleasure from destroying things. On the internet you may call them trolls (from the harmless garden variety, to the people swatting, making death/rape threats) - depending on the variant, you may eject them from the community, shadowban them, call the police, etc. All of which are applications of force and authority. How do you deal with those people, when you go outside the safe confines of the internet, without using force or authority?
