I think shelter is important and yes it is normal to live at home with your parents (for girls) until you get married.
Folks with different upbringings where their parents abandoned them or split up, or didn't care for them or let them do anything they wanted, they won't know any different but they might be ashamed of their way of home life.
I think it's the homeschool thing that would be most polarizing since, if you have only been homeschooled your circle of people you hang out with would be more just your family and relatives.
those of us who weren't homeschooled have always needed to fit in somehow in a class of 30 or so others who are not closely related to us lol.
If you've ever seen the movie Mean Girls, you'd see how high school cliques could operate. It was originally meant to be called Homeschooled, it was about a teen girl called Cady who goes to high school for the first time, before that she was homeschooled in Africa. Her first task is to make friends....everyone kind of treats her like this exotic creature, she tries hard to fit in and seems to lose herself in the process.
In my country, homeschooling is only necessary if someone lives too far away from school, like in the country or remote area, or maybe the children have some sort of behavioural issues like autism and they'd get bullied at a regular school. There are not so much the religious types who distrust every single thing the Government does, like public schools! There are also private Christian schools, Catholic schools, and schools that have a christian ethos or at least good values taught.
I help teach Christian/Biblical values in public schools.
