I've done my job for a long time and I'm really good at what I do (as I should be).
Football referees have also been through the 'learning process' and should be more than competent. There is, in my view, no reason why 'en masse' they can be accused of being 'grossly incompetent' unless there is something else at play. Especially given that you don't hear fans of rugby, cricket, snooker, et al accusing officials of the same thing.
Just listen to ex-referee Dermot Gallagher. A push in the back against a 'Sky darling team' in the penalty box is, without any discussion, a penalty. If it's not a 'Sky darling team' it is 'a coming together' or 'it is the referee using his common sense' or 'we don't want to see penalties given for that' or 'there wasn't enough pressure on the back'.
Doctors are not accused of being 'en masse' 'grossly incompetent'. Likewise; lawyers, accountants, dentists, truck drivers, taxi drivers, shop workers, mechanics, etc.
I just think that it's all a bit wrong and is killing the game we love.
