hmm.. as an adult, Im now a fan of not letting them see too much. us? we didnt really go to the movies, save for once or twice with our dad, and then it was a real treat and quite the bonding experience.
for our movies at home - our mom was on a zero sex/violence policy, but our dad was like "anything except outright pornography goes." so her rule reigned supreme, and we didnt see any movies (and definitely no tv) until we were like 9yrs old, and then his will reigned supreme after that. I think they had a nice balance between the 2 of them, and it worked like this: if she was seriously against a movie, she would watch it first, and then say no or maybe. if she told us no and we really REALLY wanted to see it, she would tell us WHY we shouldnt watch it, and we either would, or wouldnt, depending on our dad's mood that day.
so.....we totally saw things that would make a small child tremble. in fact, we often had nightmares, and she would laugh and tell us to stop watching scary movies. and by scary, I mean your typical Jean Claude Van Damme movie, or scifi horror like Alien. Alien gave me nightmares for months, but I was hooked after that.
We had never been allowed to watch gore horror, but our "interesting" uncle felt we were too sheltered and allowed my older brother and I to watch Friday the 13th when we visited (he had an extensive porn collection as well - thankfully he didnt offer that, though come to think of it, i wonder what he wouldve done had my brother asked.). I can remember very clearly knowing that I couldnt handle watching Friday the 13th, and telling my brother this, but he watched it in front of me anyway. I had nightmares for years and to this day cannot watch Friday the 13th. Even when I was able to enjoy Jason, I could never watch anything with Freddy Krueger.
still, we didnt watch tv, and we had to do the nighttime sneaking to watch real 80s/90s gore horror like Jason, or stuff like that. It became a rite of passage to sneak our friends movies into the house at night, then sneak downstairs for a sibling powwow and watch the movies without getting caught. There was the combined movie terror, and getting caught terror. It was a lot of fun!
Strangely enough, Im the only one I know who still watches any version of horror - at this point none of them can even stand mild horor like Resident Evil.
So no. I would never let my future children see some of the things I saw! I dont see anything wrong with the rules stopping children from seeing too much gore or violence or sex. I think it protects them. As children, I always knew we knew far more than our friends who hadnt seen what we'd seen, and now, as an adult, Im not that comfortable with a child the age I was knowing what I knew. I joke with my dad about "
how could you have let us watch that??" I know for a fact that some of that stuff shaped my character and the character of my siblings. Definitely the way we thought and saw the world.
I guess I think that children are going to do everything they can to get around the rules, and probably succeed in various cases. And that's ok, so long as the rules actually exist to protect them. I am not a fan of having children so sheltered they are gullible, but I think with rules in place, they will end up seeing some things you dont want them to see, but they will understand the context of it, based on whether they had to sneak to see it, or simply just watch it outright.
plus, I think it helps to talk to them, and to explain your reasons - even if they dont agree with you then, they will have the necessary tools to protect themselves later (e.g. if they are scared to look under the bed, they can correlate it to having watched a horror movie that night).
