Plenty of people will get angry about made up stories of children being abused.
Those same people do not seem to do much about feeding hungry children in their area, or supporting them when they are abused by parents or guardians.
This single example makes me question to what extent humans can be said to generally act based on a defence of their own moral integrity.
Clearly some people do, and more people try. Whether they "generally" do doesn't matter. What's important is that "enough" people do to prevent humanity from selecting one of our myriad possible self extinctions.
