Also, I think this all depends on the person in addition to the identity: both what someone believes and their epistemic/psychological characteristics are relevant to whether they should identify as [whatever]. So I would certainly believe you that you shouldn’t currently identify as a longtermist, and I might be convinced that a significant number of self-identified longtermists shouldn’t so identify, but I highly doubt that nobody should.
