Etiquette - Educating the Fish

[Freudian]

You are correct that in the vast majority of cases the coaching is done to berate the fish-who-won-the-pot-with-a-silly play. And then of course it is in your own interest to shut up the coach.

But if a fish asks a poker question (should I raise with KK preflop?) and someone answers them honestly, there is no real damage done. The improvement done to the fish's game is minimal and the mood at the table is if anything better, and not worse. Yet the the most rabid "i'm a good player, let's not educate the figh" players would react to the honest answer in this case.

I don't particularly appreciate those that out of the blue decide to hold a poker lecture at the table, but answering questions from fish is ok with me.
