The Holy Trinity ?

 Back in the day, there were three people one could not speak poorly of.
Many Black homes displayed an image of the 'Holy Trinity' of the time.

While there are no posters devoted to today's version of those deemed too sacred - many within certain Black communities will fight you tooth and nail if any critical utterance contains the names of thee hollowed beings.

(But what seems odd is that so many Black women are quick to jump on Oprah.)
