Can any good come from engaging with internet trolls?
"Q: Should I ever engage with my trolls?
A: Firstly, let’s settle on a definition of “troll”. A troll is not someone who makes you feel bad. It’s not someone whose opinion you find offensive, or a “devil’s advocate” who assumes a position contrary to your own with the intention of stirring up trouble. That person, while annoying, is called an opinion writer and can still be usefully engaged with. A troll, on the other hand, is someone whose gratification is vested in an intent to cause harm. Why on earth would you engage with that?"
