The right attacks each other directly and aggressively, the left attack each other vaguely but theatrically. A conservative is more likely to go the route of "No fuck you, you're stupid as fuck because x y and z" and maybe hammer it home a few times, and a lib is more comfortable doing all that shit that happened to Will up there, just little piece here and there that make up one slow-brewing up very heinous "thing they did". I don't want to describe it as passive-aggressive, since it's generally immediate and explosive, but whatever the problem is isn't usually really the problem, if that makes any sense.
