As a homeschooler, I think the people like you should leave me and the education of my children alone! If someone comes by to “audit” me, they will be sorry.
Perhaps if the Home School Legal Defense Association provided independent audits. There are many ways to work it where you won’t be offended or threatened. You just have to get active in your school district.
But if you’re a home schooler, I support random audits, including teachers in public and private school and students in public and private schools to ensure they are meeting or exceeding academic standards.
