"As a Catholic, if I go to my local Catholic hospital, I am fairly assured of treatment by a Catholic doctor, and certainly treatment in line with the moral norms of the Church."
I see. So when you get in a car accident on some highway and need immediate care to save your life, you'll insist that they take you to a Catholic hospital even though it might be 3 times as far as the nearest hospital? Well, good luck with that.
It would probably help your understanding if you didn't work off the assumption that Catholics were ignoramuses. Nothing Herman said would lead a reasonable person to conclude that he would turn down emergency care from a competent source.
For elective care we are free to elect doctors and hospitals of our choice. Is that difficult to understand?
