I find this incredibly encouraging. Once they take the step of homeschooling their little one, several things are likely to happen. First, they will have taken a massive step towards Reaction. Homeschooling a child is a pretty explicit acknowledgment that there are limits to one's submission to the Cathedral. The second thing is that homeschool families tend to become larger. I suspect part of this is that the marginal cost of additional children once you've gone ahead and restructured your family life and economics for homeschooling is pretty small. This in turn tends to drag the family further towards Reaction. Approaching Reaction from what Americans deem the Right is not the only way to get there, you can also approach from what we call the Left, especially the 'Old Left'.
As the fraction of non-public school children increases, support for the accursed Cathedral public school system dwindles. We already see this reduction in public support as the various states have been squeezing the teacher unions to make their budgets balance. Bringing a bunch of SWPLs into the orbit only accelerates this positive feedback process.
