I work adjacent to education, and as such see a lot of high school transcripts come across my desk. The bad news is that there are absolutely tons of bad actors who use homeschooling as a way to indoctrinate kids to their insane, unsubstantiated worldview.

The worst news is that there's a ton of private schools and even some public schools doing it too. Schools across the U.S. are teaching creationism as fact, climate change as theory, and some of them even have the gall to consider their "Biblical Science" classes as honors level. If your only argument against homeschooling is indoctrination, it's not a very good one. In states like Utah and Oklahoma, you'd almost have to homeschool your kid just to make sure they're receiving a real education.
