I was homeschooled for 1.5 years, and while there were aspects of it I really enjoyed, it is absolutely rife with religious fundamentalists. My biology book used the "how many monkeys would it take to write the Bible randomly" as an argument for intelligent design. My mother didn't vet the books well because she was getting help from a Christian friend of hers.

Unfortunately, looking from the outside in, the teachers care but the administrators do not. While I would still consider public school, I think supplementing and supervising their assignments is the minimum a parent can do. Homeschool just isn't feasible for many people, and there is a reason teachers specialize in topics past grade 5.
