Yes, literally. We do the same when we discuss traffic laws. We're all part of the same society, you have the right to take whatever action is in your child's best interest, but that DOES NOT necessarily imply that everyone else must get in alignment with what you think is best. The city doesn't need to install roundabouts at every intersection on your school route because you knows it to be safer than the traffic lights. That's ridiculous. Maybe they should, but its a discussion that will require you to think about resources and about risk.

Externalities are real, and as such the discussion is about acceptable risk. So yes, in the most ridiculous and obvious sense it includes your kids, but you're assuming a lot too, and I question whether you're willing to reason critically - rather than emotionally - about school policy.
