One problem is that you aren't allowed to make mistakes in social situations anymore without facing extreme consequences, and you're right that it isn't the sort of thing you can learn by reading about it. There's really no chance for young'uns to learn in this day and age.
It's tough, and the worst part is that there's no way out or hope for things to improve. And you can't complain or seek help, or you get treated like someone who must be broken to feel that way. It's an impersonal and judgemental world that we live in today, no matter who you are or what your views are like.
No wonder so many people seem to feel that our current culture and society are so vehemently toxic that they aren't worth even trying to participate in.
