First, let me say that one-track homeschoolers can do a great job teaching their kids. I think many parents can be good homeschoolers if they are willing to commit the time and resources necessary. What concerns me is that more people might homeschool because of recent issues like Supreme Court decisions or California's new vaccination law.
It's easy to say you're going to homeschool to avoid curricula you don't like or because you won't vaccinate, but people don't always seem to fully understand that they're not just avoiding something by homeschooling, they are choosing to take on complete responsibility for the academic education of their children. You're already responsible for a lot of things as a parent whether you send your child to public school or not. Homeschooling is not merely an extension of parenting, it is an additional and extensive set of new responsibilities.
If you're homeschooling or thinking about it, you have to be realistic. Yes, you won't have to vaccinate, but you will have to figure out a way to make sure your child is prepared for adult life. This is going to take either some significant time on your part or some money, or both. You cannot hand your child books from the library for 12 years and expect them to be a competent adult. You can't send them to the Internet to find their own free curricula and expect them to be ready for college and to support themselves. There are stories out there of that happening, yes, but they are the exception, not the rule. You are the responsible party here even if you think unschooling is the way to go (I am not a fan of unschooling, but as with just about anything, a committed parent can make it work well- it's still about you). You are going to have to make this happen.
No matter how strong your ideals are, you must be prepared for the possibility that your children will end up in public school sometime because of the health or financial situations of the parents. One of the nice things about homeschooling is that you can work with your child at the level they're ready for, but this can be taken too far. Neurotypical homeschooled children should be working at least somewhere near grade level. Don't listen to the people who say that homeschooled kids can't be behind. They most certainly can be. If they're behind when you're functioning well, they will be lost when things get hard for a year, and they will. Home life and circumstances always affect schooling, but it has a far greater effect on homeschoolers.
I know you're serious about your ideals and what you're trying to avoid. Just be as committed to what you're choosing to take on because it is not a small thing.
