Came across this guy (Jeff Till) on a School Sucks podcast... He has an amazingly concise and wonderful case for keeping children out of government school, in the form of 54 arguments. It is probably the best source I've found as an introductory offer to people unaware of the importance of keeping children out of these destructive institutions.
