I have been following nutnfancy for about 4 years now. Referring to point 3, I am not so sure if he is dictating his kids' childhood. Some indications I have got from him is that he would like the knowledge and physical handling of firearms to be passed down in the nutnfancy family. I recall in previous videos he mentioned this was the family tradition and he wanted to keep it alive. So is getting your kids interested in what you are interested in, a form of controlling their future?
Also his kids and been on multiple adventures such as hiking, run and gun, motorcycle, camping, etc... so it seems to me that they have lots of good family memories together. On his elder son tactical doodle's channel, he posted a video saying how nutn spend a lot of free play/ role play time with toys etc... with him ( there is a play time that lasted 3 hours or more). Tactical doodle also mentioned that nutn would put away his supernintendo for months which is in accord with nutnfancy dislike toward video games. I would say he did his best in parental involvement. But for most parents who send their kids to school, peer influence would be a huge impact (downside) on the child especially when it comes to video gaming... I am still not so sure if he failed in terms of preping his child in terms of playing video games because I don't know how much time they spend on video games per day,week, etc...
hope we will have a good discussion
