This, frankly, flies totally contrary to the idea that parents need to do more active parenting. If you don't have the time or ability to debrief your kid after they consume age-inappropriate media, you shouldn't be exposing them to that media, whether it's movies, books, or games. Some kids have the ability to cope fine with e.g. violent media younger than others, and if you (gen) know your kid can handle a game intended for an older audience, fine. But encourage parents to know what's in the media they allow their children to consume, and to be ready to talk to their kids about it if it seems to be upsetting the child.But seriously, people having to "hide" anything that's "too scary" for hellspawns, don't. I played Resident Evil 1 when I was 8, I played Resident Evil 2 when I was 10 and I played Silent Hill when I was 11. Only reason I ended up with issues with Silent Hill 1 is because the NTSC-J nd PAL versions had censorship in place, which played with my broken mind for years.
But, I overcame my fear. If people aren't exposed to what's scary, how the hell can they deal with the real world? I've SEEN two pepole die in front of my very eyes, and even though it really sent my depression further into a black pit, I clawed my way back out. I have some good days, some shit days, but it's made me a stronger person for it. When shit goes wrong, I'm like "meh", because I'm so laid back now, because of the shit I went through and it has made me a stronger person even if I don't feel like it most days, but I'm still here, and alive.
It doesn't mean that it's productive to wrap the world in cotton wool for your kids, but a little bit of care to make sure they're not exposed to more than they're equipped to handle helps them learn to cope with adversity better than just letting them get in above their head.
Expecting others to do your parenting for you, whether it's pressuring Google to sanitize YouTube or bitching about people in assless chaps at Pride because you don't want your kid to see some random leather daddy's buttocks, is absolutely no bueno, though, no argument there.
