Came here from Anarchyball! Thanks for the write up.
I think that these conversations are important, and when my daughter was born it felt like one NAP violation after another.
We chose vaccination (wouldn't choose circumcision if we had a boy) and I think it is the best choice. If vaccines wear off after ten years that seems about the time our kids stop interacting with each other in unsanitary squadrons of toddlers and kids and are clean and less prone to sticking their fingers in each other's mouths en masse.
Anyway, as an AnCap I understand that my values and decisions are my own and belong to me and my family. I wouldn't demand another person vaccinate because I think they should. That's up to them and their own.
Followed and excited to read more of your stuff. And I'll still see you o we at Anarchyball!
