You touched on it in your report, but this is a bit deeper than proving one’s faith.
No parent should require an exemption to teach their children and protect them from the rot and filth that is public education.
Even though I am a Christian, the idea that one can only school their children for religious reasons is abhorrent. Home schooling is the right of any parent, religious or otherwise.
I understand the accepting of the exemption law to get through the circumstances of the time - but that exemption implied the state’s authority to deny parents the right to protect and educate their children...a right the state most emphatically does not have.
Any of these attempts to force children into public schools should be universally met with a firm “Butt out!”
Here in Texas, if one wishes to homeschool, you just homeschool. In metro areas such parents have gotten together to foster team sports and the like with other homescoolers.
It is surprising how many state academic prizes (spelling bees and math olympics are won by homeschooled kids.
