And try to drag down a good one.
True.
A Good Man shines a light on their own lack of morality, inadequacies, pettiness and ignorance. They must drag the Good Man down so that the world at large might not notice their lack of morality and take them to task for it.
Instead they raise the bad up, call evil good and wrong right.
We say shine the light on the Good Man so all may be heartened by his faith and have knowledge that goodness will prosper.
