The internet originally designed a booster of human intellectual abilities has become an amplifier of human emotions especially negative emotions which makes reflection more difficult.
On the one had people in the comments are talking about gore threads and snuff that they found on the internet messing them up. Which is fair, that would mess anybody up. On the other had my dad once talked about seeing live tv broadcasts of people being executed by Fidel Castro's revolutionary government, and how that messed him up as a kid. That was way before the internet. I don't think we can blame just the internet on us being messed up in the head. It's been going on way longer.
