I don't think anyone is asking for refereeing perfection and don't recall seeing that ever suggested. What I am hearing is a call for consistency and 'fairness', which I am confident could be improved in one fell swoop by minimising the number of arbitrary/discretionary decisions.
Putting that particular hobby horse aside, some genuine information/communication [i.e. not spin/PR] about what is going on in the world of NBL officials, what they are trying to achieve, how the administrators are working to improve the situation [assuming they are], and so on would help improve perceptions and understanding. So too would some accountability, like the referees coach/manager admitting when there has been an issue, when there is a current 'focus' and so on.
As previously acknowledged no-one is perfect, so one of the constant irritants is the nonsense position that referees can do no wrong or are never wrong. Everyone makes mistakes, so it is nonsensical to suggest that no referee ever makes a mistake, which seems to be the standard position. Admitting error - at least from time to time - would be a significant step towards improving understanding of the official's lot and winning public support/sympathy.
Of course, it would help if coaches and players set out to play/operate within the rules as much as possible instead of pushing the limits, which immediately puts officials under pressure and ultimately on the defensive. As a simple example, if a coach coaches/drills legal footwork there will be less travel calls to arbitrate; if a coach coaches legal defense and good screen technique there will be less illegal contact to arbitrate.
I agree that respect is important, but it is important to realise that you get respect by earning it, not by demanding it or by tech fouls [though I'm not against a good tech occasionally] and the concept of earning respect might be something the officials 'powers that be' might profitably spend some time working through.
That said, maybe the officials, coaches and players, perhaps through the players' association, could agree to respect each others' roles and agree that officials won't coach ['stop holding', 'hands off', 'straight up', 'don't block'- they're there to make decisions and blow the whistle, not tell players how to play; the player and the coach has already decided that] and that the coaches and the players won't referee - which could be limited by the officials not entering into discussion with coaches and players during the game, which must break their concentration and so I suspect is contributing to the issues being raised in this and similar discussions.
And reviews, whether initiated by an official or a team/coach are NOT the answer in my opinion. The few we have now delay and disrupt the game, destroying tempo and momentum and I'd get rid of all of them, whatever the NBA does.
