Nobody needs to grow up purely because they have a different opinion.
Nobody is saying we are always on the end of poor decisions and never get any in our favour, nobody.
Nobody is blaming teh refs for being infallible, they make mistakes, the purpose of VAR isn't to blame them, it's to help rectify them.
Nobody is being entitled, some people value the idea of improving decision making, nothing more.
I've read posts from those against VAR complaining about decisions in the past, that's being negative is it not?
The issue is there is no way to say they even out, it's an urban myth. There is zero evidence for that. you could get a decision go against you that ends up in relegation, then 4 months later get one in your favour that sends you to the 4th round of the FA cup, is the impact the same, no. But apparently they've evened out.
That's exactly my point, if you ignore factors like size of club and media/fan pressure that might influence poor decision making, and take every club as being equally treated, then there is nothing limiting to this "decisions even themselves out" being in the same season. So you could miss out on europe or get relegated due to a poor decision, and then get a meaningless decision in your favour the next season that evens out and gets you one place higher in the midtable in a lower league. Yes, technically you've had one go in your favour and one against, but the impact hasn't evened out. The impacts of poor decisions in this sport can be huge. It's generally a low scoring sport, where the chance to recover from poor decisions is fairly small, the costs in terms of loss of revenue or failure to get promoted can be huge sums100m plus.
