I don’t use troll in the pejorative sense. Actually, I may be trying to craft a neutral meaning of troll where none previously existed. The term, in its modern Internet usage, refers to people who want to start fights online to bring the universe into an argument on their terms. It comes not from Grimm literature, but from a fishing technique in which multiple lines are baited and dragged to haul in the maximum amount of cold-bloods.
When the conventional liberal media give endless coverage to one stupid comment by a Republican Senate candidate, that's endless, headline making news. Obvi. And when conservative media do something similar with something as self-evidently meaningless as the Democratic Party platform, that's trolling. Whatever.
