Who could say? Societies seem so strange over time, we look back at the Greeks and such and we think they're insane, but for some reason, they saw nothing wrong with it.
However, I do think people are going a bit overboard with the whole child-protection thing right now, people being told off for taking pictures of their own children, kissing their own children on the head.
Children are only stupid if you don't educate.
"Timmy, if a man or woman comes up to you and says he or she wants to get in your pants, he or she wants to use you and that's against the law. Not too many people want to, but some do. Watch out for them."
Just use that paragraph, name not withstanding, children have got a lot of the protection they already need, knowledge is a lot of power.
Children are "weak" because we invented childhood for modern times, if we just inform them of what they need to know, they'll be fine.
Also, notice the invention of "childhood" made the paedophile population seemingly boom? Yeah, might be something in that... attempting to hold onto the idea of innocence and youth, people do strange things.
Making up the idea of innocence with youth, well, it might just be responsible.
And I know children are not innocent, I was thinking of busty ladies aged eight.
