Who’s “y’all”? Religious fundamentalists? There are other people who homeschool. I did it for a while and now that my kids are back in school - they wouldn’t be if circumstances allowed - they are way ahead of their peers in terms of understanding the work they’re given.
And “smart enough” implies school is doing something special that children need, but it just isn’t. Kids want to learn. It is a remarkable feat that school is able to make them hate it.
And “cutting your children off from society” implies that school is somehow an integral part of society. It just isn’t. It is the factory-prison model of school that has helped to atomise society and make us dependent on states institutions like school for interpersonal connection. There are other, better ways of doing it.
