I have been approached by some parents on occasion with a fairly complicated question:
“My kids are into anime and/or manga. What is it and what do I need to know so I can monitor what my kids are watching?”
The answer is complicated, and when I present it, it invariably provokes a lot of follow-up questions, so I'm going to present this as a sort of FAQ – Frequently Asked Questions. Hopefully this will clear up some of that confusion, and help parents make better decisions about their kids' viewing material.
