I hate these discussions.
Refs make mistakes - that is it. There is no agenda against any team, there is no ulterior motive. The game is electric quick these days, they get one (real time) view of what happens and players are constantly cheating. Add them all together and you get refs making mistakes.
There is no solution to the issue. You cannot replace them - they will still make mistakes. You cannot pay them more - they will still make mistakes. You cannot get "expert" refs in from other leagues - they will still make mistakes. You cannot introduce video technology - they will still make mistakes.
The only thing to do is to stop feeling persecuted and just accept that sometimes wank goes for you, and other times wank goes against you. Just like it has done since football (and all sports) begun.
