If a parent has too many hangups, too many fears, too many issues, that they don't take out and examine, it will destroy what unschooling could be. People can get really wrapped up in fears and "what if's". Sometimes it consumes a person, a parent, a family. Happy, peaceful, unschooling can't flourish in those conditions. Fear creates blocks. Learning needs easy flow. Easy flow can happen naturally unless a person blocks it.
