My parents denied me all kinds of things my friends were doing when I was a kid and looking back they were absolutely right to do that. Don't be afraid of that.
Sure they made mistakes here and there. The names of Pokemon aren't actually names of demons. Looking where a lot of my friends ended up though I think they got things right on balance.
Same here. It was movies and TV for my parents. I have thanked them for it on several occasions when it occurred to me as an adult how affected people are by having not just grown up watching various age inappropriate movies and were trained by TV in general, because their whole world view, their whole mental superstructure is extremely influenced by TV and movies.
It has clearly spread across the world to some degree, but I don’t think the average person even realizes just how much the post ~1920 American consciousness is trained on Hollywood, TV, movies. It has become a bit more diffuse lately due to decentralization of TV and movies, but the training on TV also seems to have gotten worse, even if in more covert ways because of the decentralization. You consume your TV drug in isolation and do not even talk about it anymore because everyone is watching different things at different times now. America has gone from the social drinker, the highlight of the party, to the binger I’m downs a bottle of vodka TV a day, alone.
Our culture is effectively centered around what is on the real life telescreen, the one that you carry around now, that knows where you are at all times and can listen in on you. Even Orwell could only imagine a world where telescreens were fixed and could be evaded at times, or maybe he just believed that.
Yeah TV is particularly nasty. I can't believe how much I was shielded from as a kid. They didn't have the theory totally right and a lot of it was based on their feelings but that seems to work plenty well enough.
