We're in a very homeschool-friendly community and the few negative responses we've had have all been from parents of my daughter's former classmates. My sense is they feel like we've opted out--and that by doing so we're leaving them to fix school problems on their own. Public schools are a source of such anxiety in some communities, and reflect so many race/ethnicity/class issues that the decision to HS can seem like abandonment of the schools and communities. To try and counter this we've stayed involved with education issues at the school board level, but it's a largely futile (I fear) effort, given the layers of bureaucracy.
