No, this is the danger we are in. People are letting the "marketplace of ideas" try to sort things out. However, this is like letting a disease ravage a population until it achieves herd immunity. If it has no natural immunity, it never will. Humans do NOT have a natural immunity to propaganda. They are carriers for it. We are the mosquitos of the malarial swamp of misinformation that is plaguing the planet currently.
Many folks at Facebook know the terrible plight we are in. But there are enough people not wanting to rock the boat currently that they have not felt the urgency to change. It feels like we are reaching a breaking point, though.
