why homeschool?

The comments on one of snidegrrl's posts got me thinking about how we choose to educate our kids (among other things). Her post is actually about gender assumptions and childrearing, but she brought up a question a lot of you parents (and potential parents) could help me answer.

What is the best way to educate children if you don't want them indoctrinated to think things like "girls are pretty", "boys are strong" and "everybody's white and has exactly one mommy and daddy"? I'm not talking about - despite what some people may immediately think - using your child as a political tool; rather, I'm thinking about protecting our kids so the choices they make aren't based on the "norm" but on what they want.

I tend to think that homeschooling is the answer (for a variety of reasons), but I don't have kids or even plans for them. So, I'm curious. For those of you who've given this more thought, what do you think are the best schooling options for your [real or hypothetical kids]? And why?
