Deconfusion and Disentangling EA

This 3-part sequence is intended to help me, and hopefully readers, make sense of Effective Altruism as not a single idea or philosophy, but as a set of related philosophical ideas, causes, and communities. This is important, among other things, to avoid a Happy Death Spiral, and to keep your identity small. Ideally, approaching this with a scout mindset will allow us to separate different parts of EA, and then feel comfortable accepting some things and rejecting others, or assisting people in embracing ideas without uncritically accepting the entire edifice of EA.
