When we ran into local and state folks trying to make rulings about homeschooling it was usually someone beholden to the teachers unisons spearheading it.
So homeschoolers showed up.
Our political class learned that on should never pick a fight with a group of committed and motivated people, who have all day, and can make the fight a unit study, on government, or philosophy, and give high school credits.
Just like HR6.
Every time someone goes after homeschoolers, they find out that for such a loose knit, independent minded group of people, they are a force to be reckoned with.
