"Personally I take an interest in what my kids are watching and we talk about it openly." <- Exactly. This is how it was always done. You went hunting, it wasn't "here's the spear, don't get hurt". You showed, you talked through it (we can pause a video and talk about their perspectives, etc) and very importantly, using the gunting example, talked about how the killing affects the animal and use spiritualy. Such a privilege to be a father, investing in our kids (even those without it can help in the community) is how we ensure they have the best chance they aren't scammed by poor mentors in life.
