Wow this is really disturbing... I do not have kids myself, but my brothers and sister do and they are all at a very influencial age... One of them is also authistic and I don't even want to think, how hard this shit will fuck that nephew up because they already have a hard time keeping fiction and reality seperated... I really need to make them aware of this, therefor alone I thank you a thousand times that I'm aware of this sickness now
No young kids for me either and I have been doing my best to get this out to places I hang out online where parents also attend. This is something you do not need to really push. All you have to do is tell the parent to look in the sidebar of suggested videos. Two minutes effort will open the eyes of any normal human.
Best of luck to you in helping your family. I have heard of one parent whose kid went ballistic for a few days after she took it away - he was "addicted" to You Tube, did not want to watch anything else, or do anything else. After some hard days - the mom said she felt the crisis was over while still worrying about whatever he had already seen.
