This is huge. For my own part, I shut down Facebook because of this very reason. It wasn’t just the abuse of my privacy. It was the wholesale invasion of my mental space by videos of burning baby elephants, dogs with their paws cut off, burnt orangutans, tortured pets. It is bad enough that I know such things exist. I am helpless to stop them. But now this fecal matter is burnt on my brain. It did enormous damage to my state of mind. I had no other choice but to shut it down. Given my experience I can’t begin to imagine this writ large. We have no clue. We just don’t. We can only imagine the collective infection of the human brain with this kind of virus. We are seeing it right now, all the time.
