I understand what you're getting at, but I'm not sure I agree. In the South-West of England, rugby is very much an "every man" sport. Here in Cornwall (far South-West), it is the most popular sport to watch (in terms of attendance), at least half of the crowd at my local club would be categorised as "working class", but referees and opponents get treated with respect. Irrespective of their social status, people on the sidelines understand the standard of behaviour expected, anyone who doesn't has it explained to them quickly (I've seen it happen a few times and done it myself on one occasion). My recollection of games I've watched in South Wales is the same, although I seem to recall some pretty unsavoury behaviour on the sidelines in games / clips I've seen.Personally I value the Corinthian attitude within rugby (interestingly the vast majority of soccer fans I've spoken to would like to see their game take a leaf out of rugby's book), maybe this is because I've been brought up to behave this way or maybe because I believe in the idea of sport being a metaphor for real life, but I can follow the idea that this is a cultural thing. Even if it is considered morally acceptable, I don't see why grown men or women would want to behave like spoilt children who didn't get their own way or like the audience of a pantomime.- - - Updated - - -Luckily the Twickenham crowd isn't representative of the English rugby watching public, although you're right that their behaviour is terrible and being at the national stadium, a poor reflection on the English game. One of the many reasons I'll leave Twickenham trips to the corporate beanos and once a year watchers and enjoy spending my time on the terraces of proper rugby clubs, enjoying the company of proper rugby supporters.
