> It's not in the best interest of other children to let your children not be immunized.
This doesn't change my point at all.
First, the idea that my child should be subjected to something harmful because it's better for other children doesn't fly with me. I doubt it flies with anyone. I vaccinated my kid for her benefit and for everyone else's, but if the choice is "everyone else" or "my kid"... I don't think you have to be a parent to see how that one shakes out.
Second, that's not how anti-vaxxers see it. They see it as bad for those children as well.
