Some of the detritus from The Left Coaster has accreted in a previously unknown depression of the blogosphere called Low and Left. Here's some advice from "DJ Moonbat" on dealing with "trolls":
If addressing a troll's point advances the greater good (i.e., making them feel stupid and inadequate, and thus bringing them closer to true understanding), by all means do so. But if all you hope to achieve is correcting a misunderstanding, or educating someone who seems horribly misguided, or getting an emotional cripple in touch with the fundamental decency that should underpin human existence, forget it. You're not dealing with sane people.Translation: if you're sure you're right about it, correct your opponents' grammar and/or punctuation. Otherwise, if you are faced with someone who actually knows what he's talking about, try to ignore him or use ad hominem attacks to distract your friends from seeing you exposed as the partisan hack you are.
