The risk to innocents is real. Physical security is a really hard problem for people in this space, and the police won’t protect those at risk. Does one post on one rationalist website really matter? Yes, for the same reason your vote matters at the ballot box. This is the collective action problem. If nobody self-censors a statement that puts people at risk, the risks only increase over time and those who help propagate the info are morally culpable.
In light of reading Hazard's Shortform Feed -- which I really enjoy -- based on Raemon's Shortform feed, I'm making my own. There be thoughts here. Hopefully, this will also get me posting more.
