But everything else, no. It's nihilism just people unaware they live in a nihilist mindset.
Only if you define "nihilism" to mean the exact opposite of what it means. Every single ST series produced by Paramount+ has argued strenuously that our actions have moral value and that that value matters. Every ST series produced by Paramount+ has argued strenuously that betraying morality is a bad thing. That is the exact opposite of nihilism.
Nihilism is basically the notion that humans are just meaningless lumps of protoplasm on a flying dirt clod in an empty and uncaring universe, and everything that happens, from true love to mass murder, is just chemical reactions in that protoplasm. Any notion that anything about humanity has any inherent value is anathema to nihilism.
I have no great love for either philosophy, but I can tell the two apart, no problem.
Your kids are a blank slate, they are gonna adapt to what they're exposed to.
Nope. Kids' personalities are a result of a complex interaction of both nurture and nature, and trying to argue they're a blank slate is just nonsense.
Tabula rasa, the blank slate, is a popular notion. However, it's not completely true. My developmental psych professor taught that children are active constructors of their environment from birth, by very real qualities they bring to the table.
So, the old proverb "what's bred in the bone comes out in the flesh" is not entirely false.
If you want them to stay in the basement all the time just give them an iphone.
Well, they might come up for food sometimes...
you never know what kind of kid you're gonna end up with. you never know if your kid will be prone to addiction, violence, sexual assault, vulnerable to getting raped etc.
All you can do is be careful on what you choose to expose them to.
True. But it helps to know the difference between what is harmless and what is destructive. My mother's presumably well intentioned rules kept me away from car chases, gingerbread houses, and G-rated cartoons. Harmless stuff, all of it.
