To the OP:
“Can you understand that we never entered an agreement that I, who oppose vaccines will get vaccinated, to help protect you?”
Lets assume this is a halachic and hashkaficly sound statement: What if I rewrote the sentences as follows:
Can you understand that we never entered an agreement that I, who do not have a child allergic to peanuts will stop sending peanut butter sanwiches with my child to school to help protect your child? What is your response?
