But even morality has to realize wisdom. Acts that make a situation worse are self defeating... better that he do the equivalent of a sit down strike (or quit) than to stir up a hornets nest without killing it or any hope of killing it in sight.
What I interpret you saying is that descretion is the better part of valor. That may be in certain situations, but I believe in this case morality trumps wisdom. It may have been wise to ignore the deprivation of a child, but it wouldn't be moral.
Jesus said that who would give a child a stone when he asked for bread. It is incumbent to protect children, especially from Muslim perversions. If one doesn't, then one is no better than the perpetrator.
