Once again I can reshare a Diaspora post but not respond in a comment...
It seems very much to depend on authoritarianism -- i.e. whether you believe that group cohesion is more important than... collective individual empowerment (for lack of a better phrase).
If the former, then it makes sense to repeat whatever beliefs the group espouses
, whether or not they make sense (and in fact the less sense they make, the more it becomes a marker of group-loyalty when you repeat them).
I recently rediscovered @Laurelai Bailey
's experience-based explanation
of how this works, and found it to match up well with my own observations.
