FB has had an undeniably negative affect on society as a whole because of its ability to let people dive deeper into their own bubbles of reality (whether truthful or not).
Putting curtains on the blinds only means the problem will get WORSE, not better. People won’t have that silly emotion called shame (not that they have much of it anyway) getting in the way of a good racist rant or news story about the end of the world or how people with darker skin are so scary.
At least now there’s a chance someone with rationality will chime in if a story gets spread far enough. In the new private FB our divide is going to turn into a canyon :(
