This is the same reasoning that gets us sex ed for kindergardners. "Oh, we have to teach them all the facts early, some parents just won't take the responsibility."

My commie brother and his hippie wife won't give their kids immunizations, either.
That's probably okay as long as the rest of us do. They can freeload off the fact that we've drastically reduced the chance of infection by immunizing our kids.
