call out culture is a thing now because for so long our culture has been apathetic.  call out culture is the alternative to going postal in the face of shitstains that won't be reigned in by anyone or their (lacking) sense of accountability or personal development.  It's creating a village code for what is acceptable and what isn't where institutions of justice have failed or become simply rendered useless by bureaucracy and expense.  yes, it indicates a breakdown in social trust often assuming that people aren't listening or don't care - only because that is often the case.  Call out culture makes the default that trust should be earned and trust matters.  Not just one's intelligence or ability to make a profit.
