Everything you need to know about the worst attribute of the internet is right there.
Apologies for the language and other content in the video, its simply being proffered as a clear cut case study of the problem with the internet.
It started with us, and now our children take it to the next level.
We are to blame. Because we're the ones that started the flame wars and sh*t talk online back in Quake and Quake II and now our children show us that they can take what we established, and, bring it to a whole different level.
We lacked responsibility. Those of us in the 30 to 40 age range, right now, for the way we used the internet when it started to become mainstream. We were the ones that established the rules of trolling and flaming and asinine behavior.
And now, its out of control, its coming back our way, and we don't like what it looks like.
Lets not blame the internet, lets blame ourselves. The internet simply reflects back at us everything we put into it.
TLDR Version: Garbage in, garbage out.
