Politics is one obvious cause of mind-killer disputes: Political disputes are not limited to standard disagreements about factual matters, nor to disputes of personality or perspective or even faction: they involve matters that people physically fight over in the real world—or at least, matters that are to be enforced by the government's monopoly of violence. Accordingly, politically-motivated people may come here to Less Wrong in order to diligently reduce their casualties and add more recruits to their side.
Another cause of mind-killers is social taboo. Negative connotations are associated with some topics, thus creating a strong bias supported by signaling drives that makes non-negative characterization of these topics appear absurd.
It may be particularly important for Less Wrong to encourage a rational perspective with respect to these contentious topics. Nevertheless, introducing these topics into an otherwise healthy discussion (for example, to present an analogy) may ruin it, encouraging fallacious modes of thinking.
