I don’t think anyone suggests the referees are cheating us - more that they are incompetent.
They (the football authorities) need to fix it and make it more consistent. Not sure if that’s better training, more money, more officials, not what i’m paid for.
I agree it's more human error/incompetence that results in the inconsistency.
But there are times where the decisions are so one sided during a single match you do start to wonder. Their players committing fouls all over the pitch and not getting book, then we do one or two and both players get booked. We have a striker backing into the defender and it's a free kick to them. They do the same and nothing is given (or even at times they get a free kick!). They time waste and nothing happens, we do it once and get booked.
Sometimes I think with the yellow cards for constant fouls maybe the ref has decided they're going to book the next player that does it and it happens to be one of our players, even though all the previous fouls have been by them. Though that I would categorise as incompetence because they should factor in who is making the fouls.
Of course there are games where get the rub of the green as well, but it definitely feels like it's fewer times than goes against us (though I will put that down to my own bias). Though having said that even in games where I'm impartial, such as PL, you do feel like certain teams get way more of the decisions go their way. For example a penalty for a team like Liverpool will never get given to a Burnley. Even sometimes with VAR the amount of time they seem to spend on some decisions involving bigger teams to give them the outcome is ridiculous, whereas other teams it's a cursory glance and 'nah!"
