Are some ideologies more objectively correct than others? (Abolitionists used ostracism and violence to prevail against those who would return fugitive slaves south. Up until the point of violence, many of their arguments were "soldiers." One such "soldier" was Spooner's "The Unconstitutionality of Slavery" --from the same man who later wrote "the Constitution of No Authority." He personally believed that the Constitution had no authority, but since it was revered by many conformists, he used a reference to it to show them that they should alter their position to support of abolitionism. Good for him!)
If some ideologies are more correct than others, then those arguments which are actually soldiers for those ideologies have strategic utility, but only as strategic "talking points," "soldiers," or "sticky" memes. Then, everyone who agrees with using those soldiers can identify them as such (strategy), and decide whether it's a good strategic or philosophical, argument, or both, or neither.
Summary: I propose we somewhat relax our stance on political speech on Less Wrong.

A recent series of posts by a well-meaning troll (example) has caused me to re-examine our "no-politics" norm. I believe there has been some unintentional creep from the original intent of Politics is the Mind-Killer. In that article, Eliezer is arguing that discussions here (actually on Overcoming Bias) should not use examples from politics in discussions that are not about politics, since they distract from the lesson. Note the final paragraph:
So, the original intent was not to ban political speech altogether, but to encourage us to come up with less-charged examples where possible. If the subject you're really talking about is politics, and it relates directly to rationality, then you should be able to post about it without getting downvotes strictly because "politics is the mind-killer".
It could be that this drift is less of a community norm than I perceive, and there are just a few folks (myself included) that have taken the original message too far. If so, consider this a message just to those folks such as myself.
Of course, politics would still be off-topic in the comment threads of most posts. There should probably be a special open thread (or another forum) to which drive-by political activists can be directed, instead of simply saying "We don't talk about politics here".
David_Gerard makes a similar point here (though FWIW, I came up with this title independently).
