I’d be interested in examples of what he watchs, it’s hard to know how to respond otherwise.
I think you’re probably worrying too much though, I watch all sorts of junk on YouTube largely because I enjoy finding out how other people think more than it constanrly changing my opinion - sure he’s young and doesn’t have the same level of awareness as an adult but also nothing in his life will actually matter for about 5 more years so a few bad opinions aren’t the end of the world.
When he says ‘I don’t know’ maybe you should believe that’s how he really feels, feed into it a bit and as painful as this might be for you admit that you don’t know either - life is full of confusing shit and honesty half the stuff I see I don’t even know how I feel about it or if it’s true, sane, or sensible. I’m sure he knows loads of interesting things going on in the world that you’re totally unaware of so let him tell you about it, be interested and accepting while in a non-dogmatic way rasising doubts where appropriate or simply tell a story from your own life that explains your doubts - not like ‘I’m old and know better’ but more friendly and demonstrating it’s normal to not know who to trust or what’s valid.
Positive reinforcement of doubt and distrust is important, demonstrate that you understand he’s learning about the world and its absurdities and complexities, laugh about some of it WITH him rather than making him feel like you’re saying ‘the stuff you watch is dumb and you’re dumb for watching it’ because understanding others is FAR more important in life than knowing the truth about obscure subjects, hard pill to swallow maybe but it’s true.
Your seven points you worry about are well and good but media doesn’t do that, politicians don’t do that, corporations don’t do that, life partners and lovers don’t do that, friends don’t do that, I bet YOU don’t do that… To live in this world we’ve got to learn how to take the important bits and leave the rest, we’ve got to learn why people do the things they do and that’s only possible with a big messy database in our heads of all the different types of people out there.
It sounds from the way you speak like you’ve given him a good grounding in logical, sensible, and scientifically literate discourse which is great but now his brain yearns to understand more of the world - why is everything so crazy and weird? why do people who seem nice sometimes do crazy and hurtful things? Why does this girl say such odd things, does she like me or hate me? These are questions you can only start to answer by understanding people and things you don’t believe in.
I listened to endless craziness like Alex Jones, 5Live, loveline, all sorts of brain rot shit - never once did I think Adam Carolla was anything but [string of words now forbidden] though he was funny, it was fun to listen to and entertaining, I learnt a lot about the world from callers and even Adam though he certainly never did a single one of your seven virtues.
Yes maybe the entertainment is more important than the content of their arguments, being able to know the truth is useful but being able to entertain friends, girlfriends, bosses and authority figures is what can turn a hard life into a great and easy one.
