There are always people who are going to find something to worry about whether rational or not. What about a white patient and a black nurse who has written about ‘black lives matter’ and the patient gets anxious because in his mind this is the same as saying that other lives don’t matter (not true, but lots of people seems to believe it)? How should the hospital react? Firing the black nurse or telling the white patient that his fears are unjustified? What about a muslim nurse being critical about Israel and Jewish patient worrying that she may be an antisemite?
