As a counterpoint, the biggest gripe of "trolling" that I have is that it prevents dialogue rather than adding to it. It's one thing to argue for say Nazi ideology in a relevant conversation with the purpose of expressing a genuine point (this would be a rare event indeed), but that is not what trolls are doing. Instead, they are invading a conversation with ad hominem attacks as well as distracting and attention-seeking behaviors. Preventing trolling does not inherently involve silencing points of view. All it should be doing is removing unhelpful, unsolicited, and off topic nonsense. Even the most evil views that I can think of should not be censored, under the condition that they are actually being discussed with the interest of discourse, for that truly is what "dialogue" is. But again, in that event it isn't really "trolling".
