Some interesting points, but I believe that professionalism is the one of the main reasons we have so much dissent and backchat. You only have to look at Wendyball.... the game with the worst record of backchat, dissent and referee abuse.... no "chatty" referees there, just a governing body that won't support referees who take a hard line.
This issue is not so much about referees, as it is about player behaviour... punish bad behaviour and the bad behaviour stops. Also, its not just rugby, or indeed sport, its endemic throughout society and it starts in school. There are no longer any real consequences for bad behaviour at school.
Students used to be severely punished if they backchatted a teacher. Now they get "time out" or counseling, instead of what they should get, a clip around the earhole or made to write "I will not..." lines on the class black/white board a couple of hundred times and given a couple of hours detention each night for a week.
Fixing this issue in rugby is relatively simple... all that needs to happen is to add a few Laws to the end of the Foul Play Law
1. Only the appointed Captain of each team may speak to a match official and even then, only when the ball is not in play (formalizing an unwritten rule)
2. Players must not talk back to a match official or offer the the match official verbal advice.
3. Players must not appeal to a match official in any way, including actions such as waving arms, making mock signals for actions such as giving cards or asking for a replay.
4. Players must not show any dissent against the decision of a match official
All four items should be part of the referee's pre-match briefing. Items 2, 3 and 4, if they happen in the game;
- 1st offence by any member of the team = penalty kick
- 2nd offence by any member of the team = yellow card for the offender
- All subsequent offenses by any member of the team = yellow card for the offender (red card if the same player commits his second yellow card offence)
The behaviour would stop immediately
Fixing Society, well that is not so easy, mainly because of the number of latte-liberal, politically correct, social justice warriors in the teaching profession. It requires a societal change and a return to some old values about personal responsibility and accountability, discipline, behaviour and consequences.
However, one of the first steps I would take is to ban mobile phones in schools.
