Given my experience of living under communist rule, I can tell you that too much consistency is bad. Having to toe the line is dangerous. For individuals and for societies, as a whole. Communism did fall, you know.
On the other hand… some consistency is needed.
Let me give you an example.

The whole world is asking China to do ‘the right thing’ about its wet markets. In Bill Maher’s terms “eating bats is bat-shit crazy“.
Why?!?
Because of what science tells us. That bats are full of corona-viruses, which are bad for us.
That’s what we say, anyway. Those of us who side with ‘science’… And who ask the Chinese to give up their traditions.
Let’s examine the problem from the other side.
‘We’ve been eating bats for ages. And nothing happened to us. Now you say that this flu like disease is produced by viruses who live in bats. Why would we believe you – and give up eating bats, if you don’t believe your own scientists? And balk when they tell you to quit smoking. To stop piling plastic into landfills. To stop heating up the planet.
To vaccinate your children, for God’s sake…’
