I see an implicit premise I disagree with about the value of improving communication within the rationalist community vs. between rationalists and outsiders; It seems like I think the latter is relatively more important than you do.
Perhaps you could explain what you mean more precisely, as “improving communication” is really under-specified in what you wrote. Communication to achieve what purpose, exactly?
I think you may be correct that I don’t value some goal as much as you do, but I expect most of the difference lies in how we each define the phrase “improving communication”.
I would argue that my approach is very much treating “improving communication to outsiders” as a very important thing—so there must be some difference in what you are assuming the goal of such communications is.
