Oh they know better - they just hope parents will continue to be in the dark about the law that says just the opposite - the SCOTUS ruling that PARENTS have the last say in how and where their children are educated. (see my post # 20)
That's why it behooves parents who home school to connect with local Home School Associations. They have fought these things through and have access to legal backup for any parent illegally harassed by the Commissars.
