I vaccinated my children.
I never thought I would really care about this until recently when my spouse needed a bone marrow transplant. Your body loses it's childhood memory of immunizations and it's a year or more before you can be re-vaccinated.

So the parents who think they are protecting their children and that it won't matter much to other children who might get these childhood diseases because most aren't fatal are making the world a more dangerous place for my adult husband.

While he is unusual I'm sure the community is full of other immunity impaired folks who might also be at risk.

It's seeming like kind of an un-civic thing to not do.
