"do you not want to see your children grow up in a society where certain diseases are eradicated?"
It is not possible to eradicate a disease in a society with frequent influx or people from non-vaccinating areas of the world.
"Aren't you just heartily relieved to live without smallpox as a threat to your children?"
Yes, definitely. That was a dangerous disease, though.
"you are deliberately keeping them away from something that could help them directly and indirectly because of a tiny, minuscule risk"
DS doesn't need rubella vaccine. It will never be dangerous for him, ever. (He had it anyway but I can't count on lifelong immunity as he was a baby).
DD may have caught it from him. If not, she'll hopefully get it in the next couple of years and be immune for life. I'll get her tested in her teens and give her the vaccine if necessary at that point.
I've said all this many times on this thread. You really need to read the thread before posting.
