For discussion of political matters? A bit late for that, I think. This train has left the station.
Has it? Insofar as it has, that’s been thanks to our own failure to tend to basic principles. I think that in order to better reach as many people as possible, it’s critical that LW avoid politics and the potential biases that can result.
I do agree that having civilized discussions even while disagreeing about politics is important. But there are other venues for that, like Slate Star Codex, and if we indeed need more of this I think it’s better to move it off-site.
The purpose of LessWrong is to discuss and learn rationality, so I think politics are almost never appropriate here. But even if we think that civilized discussion of political matters is appropriate, the post I was critiquing was not, IMO, up to our standards of civility and polite discussion.
