It's unfortunate you abandoned this discussion, but I understand. I'll defend my position nevertheless.
> It really is the parent's job.
Parents have a responsibility, but children are not property or machines that someone is responsible for that way. They are part of society, and society as a whole is responsible for protecting them. That includes protecting them from their own parents, as well as anyone else. There are entire suites of laws, courts and services established around this very principle. It doesn't even matter whose job it is, what matters is harm being reduced.
Your argument seems to be "a well, too bad, shouldn't be my problem, why should i be inconvenienced because someone's weird offspring is harmed"...sorry , I think you need to find another society without minors in it.
Honestly though, shame on you and everyone else on this thread! may the entire internet burn down before a single child's harm is justified for its continuance.
May this entire civilization burn if it continues to defend pedos and harm to the most innocent and defenseless. But I'm hopeful that reasonable voices win, and if they don't, I'd rather be inconvenienced and have this nice little status quo that's been around for only a few decades disrupted.
