You're saying that if we believe we share the same morals, then we're more likely to let things slide for the sake of harmony and less likely to hold violators accountable?
No I'm not saying that, that's your interpretation of what I am saying. What I'm saying is what I have written, no deeper meaning.
What I said is that we vote for politicians whom we are told share our morals or we assume that they do. I don't make any judgement nor prediction what happens if that happens not to be the case - either before or after the event of voting.
