I don't count on it at all. For all the shit I just said about my brother-in-law, he's legitimately a great dad to his kids. They are attached at the hip, and he spends tons and tons and tons of free time with them on their hobbies. That's precisely why my nephew is a die-hard trump supporter, it's not Trump he loves, it's his dad, which is also his hero. He likes trump, because his dad has a stupid boner for trump. I don't see my nieces and nephews ever stepping back and questioning their parents and beliefs, because they have no reason to. My brother-in-law makes his kids recite bible verses they've memorized, like he'll say a random number and they'll quote the verse, which his trump-loving dipshit friends LOVE. My nieces and nephews are rockstars in their own little trump world. I genuinely can't stand to be around them, it makes me so angry to see a bunch of honestly very bright, very smart kids spend all their mental ability being stuffed with that kind of bullshit.
My nephew came to my house around january for a weekend visit for the first time and, being in the games industry, it was also the first time he saw my home arcade. We played TMNT: Shredder's revenge on my gaming PC hooked up to the 80" TV and he clearly had a blast. So much so that he asked his parents for a "custom gaming computer" for his birthday. I caught wind and was like "hey, I have spare parts everywhere, I do this stuff professionally, let me build your kid a kickass rig and link our steam accounts and get him started on this path." I explained to them that I was around his age when I first got into computer programming, spurred on by my own mentor giving me a desktop computer (an 8088). I was told that STEM is at odds with religious freedoms, and computers are a gateway to liberal silicon valley, so they forbid their kids from ever using computers or similar technology.
I took his son out to eat dinner last week, and we were watching Olympic Basketball, and the subject of Caitlyn Clark being left off the team came up, and he, without missing a beat, said "she was left off because she's not black and thus is oppressed." Like how do you respond to a fucking 9 year old saying this shit?? I'm not gonna sit their and berate or argue with my nieces and nephews, nor am I going to be like "your hero-worship parents are dipshits" to them and break their hearts.
So... yeah, my reach an influence on the kids are limited, purposefully by their parents. I hope they eventually wise up, but I see their poor little heads being filled with brainwashing every day and it's really sticking, and I just can't bare to watch.
EDIT: That said, I'm getting my nephew a steam deck for christmas. His parents are so dumb and computer illiterate they'll have no clue he'll secretly have a PC in his bedroom. I showed him "desktop mode" of my steam deck last time and he was completely amazed.
