If you're talking about recruiting new EAs, it sounds like you mean people that agree enough with the entire meme set that they identify as EAs. Have there been any polls on what percentage of self-identifying EAs hold which beliefs? It seems like the type of low-hanging fruit .impact could pick off. That poll would give you an idea of how common it is for EAs to believe only small portions of the meme set. I expect that people agree with the majority of the meme set before identifying as EA. I believe a lot more than most people and I only borderline identify as EA.
