What is the most effective level of self-righteous outrage?

When something like the Cincinnati zoo thing happens, at what level of outrage do we start to see tangible effects? And is the expected mechanism some twist on intercessory prayer, like what is described in Mathew 18:19? If enough of the world is able to muster the strength to claim to know what actually happened (despite not being there) and to bravely condemn the mother or call for her to be killed or to lose custody of her kids, will we see the positive effects? Can we measure exactly how much it will take? And what will be the effect?

Also, what are the recommended tactics to use? Is simply saying “that would never happen to me” enough? Or should we be calling for the mother’s death? And if we can remove the son from his mother, when can we expect the resurrection of the gorilla?
