I was thinking that in a way a stronger control over violent/pornographic content might be necessary. Lithuanian new child protection law comes to mind, where they, strongly influenced by catholic society, proceed to carry out censorship on same-sex material displayed in media.
However it then struck me that banning everything that may even remotely have a negative impact on the young is simply a way for parents themselves avoid doing any parenting. The apparently contemporary way of raising the children, which is having the children grow up on their own, is so ridiculously stupid that it is almost entertaining. If that is how it will be nowadays, then why bother banning anything?
