The proper response to a troll (and there are varying definitions of troll, let's not go there, our current candidates are fully qualified regardless of which metric we use) is not to explain to the community why this poster is a pig-headed fool. That is already obvious -- tell us something we don't know.
Instead, the response should be to post a favorite recipe.
- Most importantly, it leaves the troll wondering what happened. No violent denunciation WITH CAPITAL LETTERS?!? How frustrating for our visitor. We cannot hope that these creatures will have a sudden expansion of the heart, like Mr. Grinch, so we must simply take pleasure in their annoyance at not getting a rise from Whoville.
- It derails the troll's thread. What can s/he respond? "You call that a strawberry shortcake?"
- It provides fodder (I think I this may be one of those rare occasions when we can say, "literally") for the long anticipated dKos Cookbook.
