> What leads you to believe the reason parents are willing to dedicate huge amounts of their time and money to homeschool their children is racism?

A lot of the people I know who do homeschool (the extreme majority of families I know) have openly said the reasons why they're choosing to homeschool is because they don't want their kids exposed to the other "cultures" in their area whether that be immigrants, other religions, or LGBT people.

One family I know was thinking about pulling their kids out of public school because the choir was going to sing "Dreidel, Dreidel, Dreidel" and was worried this was indoctrinating their child into another religion. Forget the fact the rest of that holiday choir event was filled with Christian holiday tunes and what that means for the non-Christians that have a right to go to the school, that wasn't a concern at all.

Not all families, I agree. I've known a few outliers who actually are exceptional teachers and think they'll do a better job teaching the kids than the local schools (and they're probably right). But they're definitely the outliers around me. Most that I've personally known are not like that, and rely on just giving their kids workbooks with extreme religious bent to figure things out on their own.
