Home crowd booing pisses me off at the best of times. 90% of the time it's based off just being upset that a call went against your team, regardless of whether it's correct or not.
I've seen blatant knock ons receive a no try call on the big screens for all to see, and crowd still boos.
In that case it's only 'technically' a knock on.
How many fair tries have we been denied? How many dodgy tries have been awarded to the opposition? Referees are human, and they need to be reminded of their frailties regularly. It is not disrespectful to keep them on their toes.
Just a few excerpts from
The Book of Barracking...
When we are in possession:
We NEVER throw forward passes.
If the ball comes loose, it MUST have been an illegal strip.
EVERY tackle against us that goes above the shoulders is a SEND OFF offence.
Opposition players who step a toenail in front of the ref are a MILE offside. "They've been doing it all day ref!"
Our kickers are ALWAYS taken LATE and HIGH. Obviously!!!!!
When we are defending:
They ALWAYS throw forward passes.
EVERY runaround move is OBSTRUCTION!
They ALWAYS walk off the mark.
Our players are NEVER off side.
When we shoulder charge, late tackle etc these are ALWAYS referred to as, "just good tough football and the bastards are ruining the game we love!"
Hope that clears things up.
