Homeschooling itself isn't the issue

There's a school of Christian thought that views public schooling/public sector rules as anathema to their morality.they also operate private schools. In a horse shoe fashion there's cross pollination with hippie wierdos on the left. This faction represents an opposition to general public health measures and childhood vaccination.

Concerns about homeschooling is more a symptom of that development. There are several good reasons to homeschooling, but a lot of homeschooling fall into that camp. By painting all homeschooling with that brush you're likely to push other people into the camp you're looking to avoid.
