Originally Answered: Why are so many people on Quora opposed to a social norm that tolerates the civil, free exchange of ideas in private venues?
The human mind evolved with a strong drive to preserve homeostasis … aka not allow identity or worldview to shift in major, destabilizing ways.
The very processes of “denial” and “dissociation” are an outcome of this evolved mandate.
It’s not just Quora … all people are threatened by information that will be destabilizing to their (deep internal) status quo.
