I think this is the first mention of the Brennan email on LW?
That is actually kind of weird... Did the lesswrong mods deliberately censor all discussion of the emails? (Out of a misplaced sense of respect for what gets the privilege of privacy? Or deliberately covering up the racism? Or the later disguised as the former?) They seem foundational to understanding Scott's true motives, it seem like the emails should have at least warranted a tangential mention. Trying to clear this up... but searching for Brennan doesn't help as an original fiction character has that name and searching for emails doesn't help as it gets the Bostrom emails.
There's more shit gems in the comments, but I think my summary captures most of the major points. One more comment that stuck out:
Yes, this is actually true, and it is a bad thing and an indictment of EA.
Edit 1: There is another post clarifying that it wasn't mostly racists (https://forum.effectivealtruism.org/posts/34pz6ni3muwPnenLS/why-so-many-racists-at-manifest ) but 1) this is sneerclub, not careful count of the exact percentage of racists and racist talks to avoid hurting feelings club 2) if you sit down at a table with 3 Neo-Nazis, there are 4 Neo-Nazis sitting down. 3) "Full" is a subjective description, so yes its valid. two major racists would be more than my quota 4) see sidebar on debate
