This isn't unprecedented, though that post had a (quite facetious) disclaimer.
Downside: Advocating intentionally breaking the law would bring negative attention to the community, and in severe cases could bring legislative action against important members of the community. This would be less of problem for the meatspace community (Meetups and such) since everything they do isn't posted online.
Advocating intentionally breaking the law would bring negative attention to the community
We are in agreement that this is an international public online forum.
To follow your suggestion would mean agreeing to never again advocate cryogenics, futures markets, same-sex marriage or adoption, blasphemy, civil disobedience, reading poetry critical of the government or other things that break the law (somewhere). Bad governments ban these things. The crime of committing them is one way to oppose bad governments.
I was thinking about the hazards of bad government, and wondering if there was a way for the LW community to do something to oppose them, and it occurred to me that we might be picking up the problem by the wrong end.
The usual way of thinking about political action is to start with one's political identity (progressive, libertarian, whatever), and that's likely to put one at odds with people who have opposed identities.
Instead, I believe there are projects which could appeal to rationalists across a wide range of the political spectrum. A couple I can think of are opposing the war on drugs and improving judicial systems. Any other suggestions?
