There's a giant difference between stopping kids having full reign on what is now essentially the whole world of information - and instant access to strangers, than there is making sure they eat healthy, help out, and don't have bad teeth .... but I'm sure you know that :)
The only difference is in parents who raise and protect their kids without needing a law...and people who want government to be mom and do it for them and are willing to make everyone else suffer for it :)
