Separate but related to community, I think your point about identity, and whether fostering EA as an identity is epistemically healthy, is also relevant to (1).
Your analogy to church spoke very powerfully to me and to something I have always been a bit uncomfortable with. To me, EA is a philosophy/school of thought, and I struggle to understand how a person can “be” a philosophy, or how a philosophy can “recruit members”.
I also suspect that a strong self-perception that one is a “good person” can just as often provide (internal and external) cover for wrong-doing as it can be a motivator to actually do good, as any number of high-profile non-profit scandals (and anecdotal experience from I’m guessing most young women who have ever been involved in a movement for change) can tell you.
I have nothing at all against organic communities, or professional conferences etc, but I also wonder whether there is evidence that building EA as an identity (“join us!”) as opposed to something that people can do is instrumentally effective for first-order causes. Maybe it does, but I think it warrants some interrogation.
I would agree that the ITN framework, and perhaps the more quantitative analysis generally dominant within EA, is not so well suited to political questions. Great for assessing the value of a marginal dollar, or helping a person decide where to devote technical skills / a career, but not so much which protest to attend or even which representative to vote for.
I personally believe that many, if not most, of the world’s most pressing problems are political problems, at least in part. For that reason I consider engagement in political movements and democratic processes to be incredibly important and meaningful and I would really encourage you to do so, if it works for you. I think all the ideas you mentioned are very sensible. I also completely agree that for the vast majority of people, there isn’t a huge, or maybe any, resourcing trade off (although this particular issue does carry its own unique political costs).
That said: while I’ve always struggled with the lack of political engagement in EA, I can also understand it. Precisely because it doesn’t fit into a clean ITN or quantitative framework, I’m not sure the community/philosophy itself is well placed to respond to political matters, as a community/philosophy. EA fills an important niche, and it isn’t that, perhaps. People come with radically different priors, evidence is less clear cut in highly complex situations, and it’s hard to establish dispassionate stances.
So as a person who cares about the world: I would say absolutely you should engage in civil society, democratic processes, and politics generally, on this issue and others. I would encourage everyone to do so, even those who have different political ideologies to me. But I would not expect this community to converge on what that should look like.
