Sycophancy/Critique Points

I wonder if there is, on average in a general population, a specific percentage amount where you have to agree with someone before you can apply a critique which does not paint them in the most glamourous of terms?

Kind of like a points system - your sycophantic X times and that earns you 10 points. Say you think they are saying something which just doesn't even mesh with their own apparent value system - but saying so would cost you more than 10 points and that's all you've earned so far? So you can't, without all hell breaking loose and them needing you to be a bad guy in order for them to main the certainty they had before.

Just trying to make sense of years of discussions. I love a points system...so easy to understand...
