"I cannot parent in ways that make me uncomfortable, to make others comfortable." http://www.getrealforkids.com/resources/real-health/vaccines/2501-my-thoughts-on-vaccines
In general I really like this statement. I think where people would disagree with is that it's not about making others comfortable, they feel that unvaccinated children are putting their children at risk.
I don't think that it's black and white, I think there are steps of vaccination, and I think much has changed since we were vaccinated as children.
