At the point where I am causing them actual harm, or placing them at significant risk of meaningful harm.
So if the antivax agenda continues to succeed, and vaccination rates drop low enough that epidemics of previously virtually eradicated illnesses become commonplace again, will you change your mind?
Vaccinations - current and future - come with an attendant risk. I don’t mind the risk attached to the current vaccination schedule. I reserve the right to decline healthcare on behalf of my child.
We don't have to see eye to eye on this but as I have said before, I will always support a child's right to not be harmed over a parent's right to harm them.
I believe my responsibility is to my child. You can say that X belief is easily disprovable, but I reserve the right to be satisfied of the balance of evidence myself before I consent to medical treatment on behalf of my child. If someone else can’t receive that vaccination because of their own health, it is that reality, not my exercise of my child’s legal and moral rights on their behalf, that puts them at risk.
I think this is disingenuous in the extreme. You can't pretend that your actions don't put other people at risk simply because that isn't your primary intention.
If a parent satisfied themselves that on the balance of evidence their child would be better off only eating one meal a day, would you support them in that? Do they not have the right to decide what chemicals they put into their child? Why is putting chemicals into their child to prevent starvation something a parent is morally required to do, but putting chemicals into their child to prevent disease something that they can choose not to do? And before you say 'because the child might not get sick', I go back to my earlier point - you don't know which child will and which child won't get sick, so why is it ok for parents to play Russian roulette with their child's life?
I can see why you think ‘accusing’ me of being a secret anti-vaxxer suits your argument. I am not. And I think I have posted here long enough for people to know that I would say so if I was.
It doesn't really suit my argument. It's just that if I really believed you were just playing devil's advocate and this was all just an intellectual exercise to you, I would probably not bother arguing the point, since you wouldn't actually be harming your children. But I don't believe that's true, and so I feel a moral obligation to have the argument in case having the argument persuades you (and, I suppose, other antivaxxers reading the thread) to make better choices.
