>>1If progressives believe you should "accept your natural body", then why are they okay with dyed hair, tattoos, and gender transition? You could say the fat acceptance movement embodies this attitude, but it isn't really generalizable as something that progressivism as a whole is based upon. I'd say that the actual principle is more like rejecting elements of mainstream culture, in that body modification isn't seen as a problem in itself, but that the concept of conventional attractiveness is inherently harmful. Like if you change your appearance only because society says you need to, you're basically surrendering your individuality even if you do it voluntarily.
In my experience, progressives seem more open to transhumanism than religious fundamentalists are, but would rather abolish the institutions they see as harmful (racism, patriarchy, etc) than benefit by conforming to them.
The conclusion of "Output: Collective Obedience" is basically applicable to all social organizations, since it's what they need to succeed and accomplish their goals. There are different names for it, loyalty, patriotism, faith, but all social organizations (families, states, religions, companies, etc) are subject to selective pressures that require them to demand obedience from their members.
