Your use of "unfairness" sticks out to me, considering you go on to say you're OK with it. Are you actually OK with the disparity or do you think it's unfairness? Can't really be both.
Unfair can simply mean not the same. Dunno about GP but this is a pretty popular sentiment. Look at e.g. GitHub saying they won't consider racial or sexist behaviour, depending on who is the offender. Look at recent popular protests in the US, where leaders organize people on skin colour.
