I really wanted to call this "For Government Functions it more important to be Impartial than Good".
The main example that sparked this off was last week the Speaker of the House Commons, John Bercow could not help but express his own views that Donald Trump is sexist and racist. Now whether he is or not is a debate for another time but it doesn't really matter because the Speaker had an overriding duty to be impartial and he couldn't do it. Same goes for the Queen and the Judiciary, the police force, medical staff and the BBC etc. We don't want to know these peoples views we just want them to do their job.
Now with the BBC I would not say they are party political biased and I thought they were surprisingly unbiased when it came to Brexit. However they do have a persistent bias towards underprivileged sections of society and always support the view that the government should do more. Now most people are in the middle of the Gaussian distribution and aren't that bothered by the lower end of the tails but the BBC thinks they ought to be, which is probably why the UK government is going bankrupt. Same with the refugee crisis in 2015 although that spectacularly back-fired. For about 4 months in 2015 we had nothing but refugees on the news. Emily Maitlis (spell checker suggested Meritless) said it was a matter of morality to help them. In that case the BBC eventually realised that seeing columns of migrants was counter-productive and simply aided the opposition to the policy. So now you don't see them much. The worst bias I've seen though is anti-Trump. The BBC wasn't able to be remotely unbiased on that one. Now as everybody has to pay the license fee it would be better if the BBC could be middle of the road or if they cant manage that be completely apolitical.
What about being good? Well the Nazis, Communists and Islamic State all think they were doing good. Feeling righteous is no guarantee. If you are happy about people being biased towards your views, what about when it goes the other way? Having government institutions and people being partisan will just split people into tribal factions and undermine people confidence in the state.
