Am I protected if my religious beliefs say I need to sacrifice a virgin? Certainly not..
Well, I suppose that depends on how the virgin was "sacrificed", now wouldn't it...
...so why should I be able to gamble with my child's life based on religious beliefs?
Because your religion says it's not a gamble. At all. It's God's will. The question for the courts is when will they start defining the death of a child as criminal. The risk of non-vaccination is not merely endangerment to the public, but can also be viewed as murder in the case of a child who doesn't know better.
Furthermore, they are MY religious beliefs, not my child's. Who is to say my child is going to give a crap about my religion when he grows up.
Uh, your religion does, by ensuring your child will go to [insert eternal damnation definition here] if they don't.
Sorry, just wanted to clarify exactly how religious zealots justify their stance today, and how that logic perpetuates through generations.
