If I know your SSN, can I shout it out on main street to anyone who will listen? Or what if you have AIDS...can I tell people that you have this disease?
The problem with those examples are yes you can say them. the question is how do you know? Doctors have a field of ethics which preclude you from telling personal info to people you don't want know, even your spouse ( I worked for Accredo and you were NOT ALLOWED to tell a wife unless she was authorized, same for husbands). Now had I don't that, I would have been fired and I could be prosecuted, because while we have free speech, we also have a right to privacy......so that is a valid question for the court. Saying you have a right to an abortion is not, it's not in the constitution. Even murder isn't in it, it's a state crime, not a federal one, unless committed on federal land.
