Blogdial reports on a US homeschooling family who turned a social worker away at their door. The usual advice in the UK is "don't do that here; it may well land you in trouble". So yes, Blogdial may well be right: a written constitution would probably help. However, the rights apparently conferred upon us by European Human Rights laws appear to mean next to nothing as the case of Melissa Busekros in Germany seems to demonstrate.
"If the British Home Schoolers do not wake up and start to get angry, they will be steamrollered and their children made into property."
He's right about the threat, though I think we are getting there in the anger stakes!
