We are just developing our "global civilizational immune system". Life is dangerous for humans. We can die many ways. How can we become safer? Assume people everywhere are good, just like body tissues, but sometimes, like disease, people or a group of people "turn bad" for "no reason". The bad things, like diseases, have ways to attack the good tissues. The good things, healthy tissues, need ways to fight back agains…
Thanks for this optimistic viewpoint. Much appreciated!
