Being polite & respectful is a skill that's good to have for many reasons. Sure!
But generally it feels like a huge disadvantage to me, bordering abuse, to see kids that accept authority as such. Here on Hacker News I think especially the long old idea of "Question Authority" should be strong. Adults don't always earn their authority, and especially in home-schooled environments I think kids are super abused into forced arch forms of "respect" and behavior that aren't genuine, aren't earned, and which are detrimental to the human spirit that we ought be engendering.
Reciprocally sure there are a lot of bad behaviors kids can pick up too. It just seems so convenient and false to me to just suppress the inconvenient signals, to deny having to form judgement. To see adults doing that feels crazy beyond measure. Judgement & sense must be earned.
That largely depends on the parents. Many are _wildly_ unfit for this.
It is, but do we have any studies showing how well school kids are at this? From what I've seen, most kids in school do not learn those skills.
Kids from home schooling families we know are as polite or substantially more polite than those in the school system.
