I've been very concerned about our schooling systems for over thirty years. Solzhenitsyn wrote that the only way to survive a totalitarian communistic society was to create parallel societies. And so it begins. I first saw it with the nursing profession and here now comes the teaching profession. Good News!
For those in urban and suburban neighborhoods, you could probably start with neighborhood watches. Then with archery clubs. Vegetable gardening societies? Food preservation and canning clubs? Two or three members is a good starting number. And keep inviting recruits. You should meet regularly and then have a private online discussion group, which I think you can create here on Slug. You only need to choose "hide group" in the selection.
